The strongest version of this comparison is the one that concedes the bedroom, so let us do that first. A reed diffuser in a bedroom is silent, needs no power, holds nothing to a schedule, has nothing that can fail at two in the morning and works perfectly well behind a closed door that no machine can reach through. That is not a consolation prize. It is a straight win, and it is permanent. Everything else on this page is about the other half of the house, where the machine wins for reasons that are just as specific.
Quick answers — read this first
Is one scent machine better than several reed diffusers? For the connected volume of a house, yes. For a bedroom, no. That is the whole answer and everything else is detail. A cold-air machine holds one register at one level across a continuous body of air, which is what a reed cannot do because a reed only affects the air immediately around itself, and it does it on a schedule so the house is already scented before anybody walks in. The SOSA Vaayu at Rs 11,999 covers approximately 1000 cubic metres with a Bluetooth app and timer and four hotel-inspired blends in the box. But coverage assumes connected air and no machine passes a closed door, and in a room that is shut, silent and occupied by somebody asleep, a reed from Rs 749 is genuinely the better object: no power, no noise, no schedule and nothing that can fail. Most villas end up with both, typically one machine plus one reed per closed room.
Where do reed diffusers actually beat a scent machine? In four situations, and they are all real rather than polite. Behind a closed door, because a machine cannot reach a sealed room at any price and a reed sitting inside it works perfectly. In a bedroom, because it is silent, has no light on it and nothing that can fail while somebody is sleeping. Where there is no socket, or where a cable would be visible and unacceptable, because a reed needs no power at all. And where nobody wants another thing to set up, since a reed needs no app, no schedule and no decisions, and settles at its own gentle working level unsupervised. They also win at the till: eight reeds at Rs 749 is Rs 5,992 against Rs 11,999 for one machine. Where they lose is scale and consistency, because eight bottles are eight registers at eight stages of depletion in eight different airflows, and the house changes subject at every doorway.
Should I buy one machine or reeds for every room? Look at your doors before you look at the products. Walk from your front door to where the family sits in the evening on an ordinary afternoon and count how many doors you pass through. If the answer is none, you have a large connected volume, most of the house that anybody sees is one body of air, and one machine covers it with a single object that can be hidden: the SOSA Vaayu at Rs 11,999. If the answer is two or three, you have a partitioned home, the connected volume is small, the machine's advantage nearly disappears and reeds from Rs 749 are simply the correct answer for your layout. Most villas fall on the first side and end up with both anyway: one machine for the connected volume plus a reed in each closed room, which is Rs 14,246 for a Vaayu plus three reeds.
The short answer
Short answer: The honest head-to-head, with the reeds winning the columns they actually win. Reeds win on silence, since there is nothing to hear in a room where somebody is asleep. They win on power, because they need no socket, no cable and no plug. They win on simplicity, since there is no app, no schedule, no setup and nothing that can fail. They win on reach into sealed rooms, because a machine's coverage assumes connected air and no machine pushes scent through a closed door while a reed sitting inside that room works perfectly. And they win at the till: eight reeds at Rs 749 is Rs 5,992 against Rs 11,999 for one Vaayu, a gap of Rs 6,007. That makes a reed the correct object for a bedroom and a guest bathroom permanently, whatever else you buy. The machine wins on different ground. Consistency, because eight bottles are eight registers at eight stages of depletion in eight different airflows, so the hall is emphatic and the dining room is faint and the house changes subject at every doorway, while one machine holds a single register at one level across the whole connected volume. Scale, because a cold-air unit atomises oil into a fine dispersion that travels with the room's air rather than sitting beside the source, which is why the SOSA Vaayu is rated at approximately 1000 cubic metres while a reed affects the air immediately around itself. Scheduling, because the Bluetooth app and timer mean the air has already settled before anybody arrives, and settled air reads as the character of the building while actively scented air reads as a product working. And visual presence, because eight objects on eight surfaces becomes one object that can be concealed in a console with an open back. On replacement, nobody wins: a second round of eight reeds at Rs 749 is another Rs 5,992, taking the passive route to Rs 11,984, fifteen rupees under the machine's one-time price, and how long that takes is not something we will quantify, while the Vaayu's ongoing fragrance has no published refill price either, so neither side gets a running-cost victory. The sensible basket for a villa is both: one Vaayu at Rs 11,999 for the connected volume, which arrives with four hotel-inspired blends in the box as Bundle A, B or C, plus a reed at Rs 749 in each closed room, which is Rs 14,246 for a house with three bedrooms and Rs 15,195 for four closed rooms at Rs 749, Rs 799, Rs 799 and Rs 849. Reeds are Morning Freshness Rs 749, Garden Bloom Rs 799, Evening Calm Rs 799, Mountain Breeze Rs 849, Fresh Brew Rs 849, 130ml from Rs 1,249, duos Rs 1,498, Rs 1,548 and Rs 1,598. Boond Rs 899 and Sukoon Rs 1,899 run the water-based Hotel Collection from Rs 299, which never goes into a Vaayu. Clean and ventilate first. WhatsApp +91 96192 18531.
The pick: the SOSA Vaayu (₹11,999, four hotel-inspired blends included in the box) for the connected living volume of a villa; reeds from ₹749 for a single bedroom or bathroom; a single room done properly from ₹899; the Aangan (₹25,999) ducted into central air-conditioning for genuine whole-home coverage.

A villa is not one room, it is a set of connected volumes and a set of closed doors, and the two need different answers. Whole-home scenting means one fragrance held evenly across the part of the house you actually live in - the entrance, the living room, the dining - running on a schedule so it is already there when someone walks through your front door, and already there when you come home yourself. The bedrooms, the guest bathroom and the study get their own quiet solutions. Nobody in the house has to remember anything.
One machine or a reed diffuser in every room - which should I actually buy for my house?
Both, and the split is not a compromise, it is the correct answer to two different problems.1. Where the reeds win outright, stated first because it is true. Silence, in a room where somebody is asleep. No power, so no socket and no cable. No app, no schedule, no setup and nothing that can fail. And reach into a sealed room, because coverage assumes one connected volume and no machine passes a closed door, while a reed from ₹749 sitting inside that room works perfectly. They also win at the till: eight reeds at ₹749 is ₹5,992 against ₹11,999, a gap of ₹6,007. A bedroom and a guest bathroom belong to the reeds permanently. 2. Where the machine wins, on ground the reeds cannot reach. Consistency: eight bottles are eight registers at eight stages of depletion in eight airflows, so the hall is emphatic, the dining is faint and the house changes subject at every doorway, while one machine holds one register at one level across the entire connected volume. Scale: a cold-air unit atomises oil into a fine dispersion that travels with the room's air rather than sitting beside the source, which is why the Vaayu is rated at approximately 1000m³. Scheduling: the Bluetooth app and timer mean the air has already settled before anybody arrives, and settled air reads as the character of the house while air being actively scented reads as a product working. And presence: eight objects on eight surfaces becomes one that can be hidden in a console with an open back. 3. On replacement, nobody wins. A second round of eight reeds is another ₹5,992, taking the passive route to ₹11,984. We will not tell you how long that takes, and no standalone waterless refill price is published for the Vaayu either, so neither side gets a running-cost claim. 4. The basket most villas settle on. One Vaayu at ₹11,999 with four hotel-inspired blends in the box for the connected volume, plus a reed at ₹749 in each closed room: three bedrooms is ₹2,247, so ₹14,246. Clean and cross-ventilate first, and keep the level gentle. WhatsApp +91 96192 18531 for a free sizing. Made in India; a portion of every order supports girl-child education through Nanhi Kali.

Where each one genuinely wins
The columns the reeds win, the columns the machine wins, the column nobody wins, and then the basket that comes out of putting the three together honestly.
Why this works at home
The head-to-head, column by column
The whole-home answer: the SOSA Vaayu at ₹11,999 - waterless, app-scheduled, ~1000m³, and it arrives with four hotel-inspired blends in the box. A single bedroom or guest bathroom starts on reeds from ₹749.
Four columns the bottle wins outright, and one room it owns
A comparison written by the side selling machines is worth nothing unless it names the places the other side wins, so here they are, and none of them is grudging. Silence. A reed makes no sound at all, ever. There is no motor, no pump, no fan and nothing that clicks on when a schedule fires. A machine is a machine: it has moving parts and it is not silent in the way a bottle of oil standing on a shelf is silent. In a living room with a television, conversation and the ordinary noise of a household, that is a non-issue and owners forget it exists within a week. In a bedroom at two in the morning, in a house that is otherwise quiet, it is a genuine consideration and it is one of the reasons the bedroom belongs to the reeds. No power. No socket, no cable, no plug, nothing to route behind furniture and nothing to unplug when you are away for a month. In an Indian home this matters more than the specification suggests, because the socket you would want is very often not where the console is, and running a cable to it is exactly the kind of visible compromise a well-finished room refuses. A reed goes anywhere, including a bathroom shelf and a nightstand with nothing behind it. Nothing to set up and nothing to fail. No app, no pairing, no schedule, no settings and no firmware. You open the box, put the sticks in and the object works, and it keeps working without anybody supervising it, settling at its own gentle level in a room nobody is monitoring. Every device in a house is a small ongoing relationship; a reed is not a device. Reach into sealed rooms, which is the decisive one. Coverage assumes one connected volume, and a machine cannot push scent through a closed door at any price or any setting, because the mechanism is air movement and there is none between a passage and a shut room. A reed does not care, because it is already inside. That single fact means the closed rooms of a villa belong to the reeds permanently, no matter what else you own. And the till. Eight reeds at ₹749 is ₹5,992, against ₹11,999 for one machine, so the reeds are ₹6,007 cheaper on the day. Across the range the prices are Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799, Mountain Breeze ₹849 and Fresh Brew ₹849 - five for ₹4,045 - with 130ml sizes from ₹1,249 and duo sets at ₹1,498, ₹1,548 and ₹1,598. The room the reeds own. A bedroom is shut, silent, occupied by somebody asleep, has a nightstand that will take a small bottle without complaint, and is a room your guests never see. Every advantage above applies at once, and no advantage the machine has applies at all, since the machine cannot get in there anyway. Anybody who tells you to put a machine in every bedroom is selling machines.
Tip: a reed in a bedroom is not the budget option - it is the correct object, and it stays correct no matter what else you buy.

The machine
Three things one unit does that eight bottles cannot
One register at one level, across a whole volume. This is the real difference and it is a difference in kind rather than in degree. A reed works by evaporation from sticks, so its effect is concentrated close to the bottle and falls away quickly, which is why scenting a large open space with reeds means placing several around it. A waterless cold-air unit atomises the oil into an extremely fine dispersion that travels with the room's air rather than sitting beside the source, so across a body of air that is genuinely open to itself, the level equalises. The SOSA Vaayu is rated at approximately 1000m³ for exactly that reason, and at a ten foot ceiling that is roughly 3,500 square feet of connected air, since floor area times ceiling height gives cubic feet and cubic feet divided by 35.3 gives cubic metres. The practical result is that walking from the entrance to the dining table is not an event: the register is the same at both ends. Eight bottles cannot produce that, and not because they are cheap. Each one is at its own stage of depletion, each room has its own airflow, ceiling height and temperature, and each was probably a different register in the first place because buying eight identical bottles feels wasteful in the shop. So the hall by the door where the air moves is emphatic, the still corner of the dining room is barely present, the newest bottle is louder than the rest for no reason anybody can identify, and the house changes subject at every doorway. A nose reads several unrelated pleasant smells as confusion rather than as richness, in exactly the way an eye reads four metal finishes in one bathroom, and in a large house the effect is that the home stops reading as one place. The schedule, which owners underestimate until they have one. The Vaayu's Bluetooth app and timer mean the house scents itself before anybody arrives, and this is a different experience from being scented while a guest stands in it: settled air reads as the character of the building, and actively working air reads as a product. Nobody has to decide anything on the evening, nobody has to remember anything before people come over, and nothing runs all night for no reason. A reed has no equivalent, because it is always on at whatever level it happens to be at. And the object count. One machine replaces every bottle in the connected half of the house, and unlike a reed it does not need to be visible to work, since what it needs is air movement rather than line of sight. A console with an open back, the space under a console table, a low shelf or a niche all work; a closed cupboard, a drawer or a position behind a heavy curtain does not, because that scents the cupboard. So the visible object count in the rooms your house is composed for goes from about five to zero. What comes in the box, which is unusual. Four hotel-inspired waterless blends are included at ₹11,999, chosen as Bundle A, B or C at purchase, and fragrance is nearly always sold separately in this category. SOSA blends are SOSA's own hotel-inspired interpretations from an independent Indian house with no affiliation to any hotel brand.

The verdict
The column nobody wins, and the basket that comes out of all this
Money is a draw, and the arithmetic is worth printing rather than summarising. Eight reeds at ₹749 is ₹5,992 and one Vaayu is ₹11,999, so the machine is ₹6,007 more at the till. Buy the reeds across the range instead - ₹749, ₹799, ₹799, ₹849, ₹849 and three repeats at ₹749, ₹799 and ₹799 - and the eight come to ₹6,392, narrowing the gap to ₹5,607. But reeds deplete and get replaced. A second full round of eight at ₹749 is another ₹5,992, which takes the passive route to ₹11,984, fifteen rupees below what the machine cost once, and a third round would be ₹17,976. We are not going to tell you how long that takes. Reed depletion depends on the room, the airflow, the temperature and how often the sticks are turned, and inventing a duration to win an argument would make every other number here worthless. And the same rule cuts against us. The Vaayu needs ongoing fragrance, no standalone waterless refill is published, and therefore no refill price, no consumption figure, no monthly running cost and no blend duration may be stated by us - not estimated, not roughly. Ongoing supply is arranged directly on WhatsApp +91 96192 18531, and it is a fair thing to ask about before buying rather than after. So neither side gets a long-run cost claim, and anybody offering you one is guessing. Which leaves the decision where it belongs. Buy the machine if your house has a large connected volume, if you want one register held evenly rather than several doing their own thing, if you want the air already settled before people arrive, and if you would rather have nothing on the surfaces. Do not buy it if your doors are habitually shut, because then the connected volume is small and the advantage nearly disappears; if your home is compact, because a single reed in a small connected space is not far from anything; or if you simply do not want another device in the house, which is a legitimate preference and not a failure of taste. The basket most villas actually end up with. One Vaayu at ₹11,999 on the connected volume - entrance, living, dining, passage and stair void - plus a reed at ₹749 in each closed room. Three bedrooms is ₹2,247, so the house is ₹14,246. Four closed rooms at ₹749, ₹799, ₹799 and ₹849 is ₹3,196, so that version is ₹15,195. If you want one bedroom done with a machine, a Boond at ₹899 or a Sukoon at ₹1,899 with a 15ml water-based Hotel Collection bottle at ₹299 is ₹1,198 or ₹2,198, and the Pack of 7 at 15ml is ₹1,799 if you would rather not guess at registers. For a large villa on central air-conditioning, the Aangan at ₹25,999 ducts into the system the house already has and is the only option here that reaches a closed room without an object inside it. Three rules whichever way you go. The water-based Hotel Collection at ₹299 runs in the ultrasonic machines only and never goes into a Vaayu, which runs waterless oil and arrives with its own four blends. Clean and cross-ventilate before you scent anything, because air-conditioning recirculates rather than replaces air and fragrance over a real source reads as concealment. And keep the level gentle, because a home holds children, elderly parents, pregnant family members and pets who breathe this air far longer than any guest does, and anybody reporting a headache is a recalibration signal rather than a complaint to argue with. We make no health, therapeutic, air-purification or wellness claims.
Tip: neither side wins on money - so buy the machine for evenness, scheduling and clear surfaces, or do not buy it at all.
The SOSA principle
The reeds win the bedroom on silence, power, simplicity and the closed door. The machine wins the connected volume on evenness and scheduling. Most villas need both, and that is not a compromise.
Eight reeds ₹5,992, one Vaayu ₹11,999, a second round of bottles ₹11,984 - nobody wins on money, so decide on the things money does not measure.

The SOSA home edit
Whatever the house looks like, the logic is the same: one scent, sized to the volume that is genuinely connected, running on a schedule so nobody in the family has to remember it. A single bedroom or a guest bathroom is happy on reeds with no power at all; the living room you actually live in wants a machine; the whole villa with central air-conditioning wants the ducts doing the work. Every SOSA system is made in India, cruelty-free and vegan, and a portion of every order supports girl-child education through Nanhi Kali. Here is where each one belongs.

Honest notes before you buy anything. Coverage ratings assume connected air volume. A machine cannot push scent through a closed bedroom door, and it never will - so a partitioned villa is not one scenting problem but several, and honest sizing means saying so out loud rather than selling you one machine and hoping. Scent the volume that is genuinely open to itself, then give the closed rooms their own quiet answer, usually a reed diffuser. Fragrance never substitutes for ventilation or cleaning. If a room smells damp, stale or of last night's cooking, open it, air it and clean it first; scent added on top of that only makes a more complicated bad smell. A home is not a lobby you pass through. Households include children, elderly parents, pregnant family members and pets, all of whom breathe this air far longer than any visitor does, which is why gentle dosing is the default at home and why the settings we suggest are lower than the machine can run. Anyone in the house reporting a headache is a recalibration signal, not a complaint to argue with - turn it down or turn it off, and tell us. The Vaayu runs waterless nebulising oil and comes with the four hotel-inspired blends; the Hotel Collection bottle is water-based and belongs in the ultrasonic machines only. The two formats are not interchangeable. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house, not affiliated with or endorsed by any hotel brand.

A note from Sonal
There is a difference between a room that smells nice and a home that has a signature, and almost nobody is told what it is. A room that smells nice is an event: you light a candle, you spray something in the hallway before people arrive, it is lovely for forty minutes and then it is gone. Somewhere else in the house a bathroom gel is doing one thing, a kitchen spray another, and a bedroom reed a third. Four pleasant smells in four rooms is not a fragranced home. It is four rooms.
A signature is the opposite. It is one scent, sized to the house, running on a schedule - so it is already in the air when someone walks through your front door, and already there at eleven at night when you come home yourself, and nobody has lifted a finger to make it happen. That is the whole trick the great hotels use, and it is not complicated: they do not chase smells room by room, they hold one fragrance across the volume people actually move through. In a villa that usually means the entrance, the living room and the dining as one connected space, with the closed rooms handled separately and quietly.
I trained at ISIPCA in Versailles and I have sized this for houses across India, and I would rather tell you honestly that your layout needs two answers than sell you one machine that disappoints you. Message us on WhatsApp at +91 96192 18531 with your home's approximate size, the number of floors and a line about the layout - open plan, closed rooms, central air-conditioning or split units - and we will give you a free sizing recommendation. I read those descriptions myself. Everything is made in India, cruelty-free and vegan, and a part of every order funds girl-child education through Nanhi Kali. Your home gets a memory; a girl gets a classroom.
Frequently asked questions
If reeds are cheaper and simpler, why would anyone buy a machine at all?
For three things a passive bottle cannot do, and if none of them is a problem in your house then the reeds are the right answer and you should keep the money. The first is evenness across a large connected volume: a reed works by evaporation and its effect falls away within a short distance of the bottle, which is why scenting a big open space with reeds means placing several around it and accepting that each will be at its own level. A cold-air machine atomises the oil into a fine dispersion that travels with the room's air, so the entrance, living room and dining hold the same register at the same strength. The second is one register rather than several, because eight bottles bought separately are usually eight different scents and the house changes subject at every doorway. The third is scheduling: the Vaayu's Bluetooth app and timer mean the air has already settled before anybody arrives, which reads completely differently from air being actively scented while a guest stands in it. Against all of that, the reeds keep silence, need no socket, have nothing to set up and reach into closed rooms the machine cannot enter. Both are true at once.
Is a scent machine noisy enough to bother anyone?
In a living room, no, and in a bedroom it is worth thinking about, which is one of several reasons this page hands the bedroom to the reeds. A machine has moving parts and produces some sound when it runs, and while that disappears completely under the ordinary noise of a household with conversation, a television and a kitchen, a bedroom at two in the morning is the quietest environment in the house and the standard against which small sounds are judged. We are not going to quote you a number, because we would rather you judged it in your own room than trusted a figure from a page trying to sell you something. What we would say is that the practical answer is placement rather than tolerance: put the machine in the connected volume where the household noise is, hide it in a console with an open back so it is neither seen nor central, and give the bedrooms a reed from Rs 749 which makes no sound at all and needs nothing. That arrangement means the question never arises, and it is what most villa owners arrive at anyway.
How many reeds would I need to match one machine, and would that work?
It would not match it, and the reason is worth understanding because it explains what you are actually buying. Coverage is not additive in the way people assume. Placing five reeds around a large connected volume does not produce one even register at five times the strength; it produces five local zones, each strongest near its own bottle and each at its own stage of depletion, with faint stretches in between where nothing is close enough. You could raise the total amount of fragrance in the house that way, but not the evenness, and evenness is the specific thing that makes a house read as one place rather than as several rooms that were each dealt with separately. The other half is scheduling, which no number of reeds provides: a reed is always on at whatever level it is at, so a house scented entirely with bottles has no way to be stronger before guests arrive and quieter overnight. So the honest answer is that eight reeds and one machine are not two routes to the same result at different prices. They are two different results, and the choice is between them rather than along a scale.
We are away from the house for long stretches. Which is better then?
Reeds for the closed rooms and a scheduled machine for the connected volume, and for a house that sits empty the machine's schedule is arguably its strongest feature rather than a convenience. A home that is shut for a week develops that closed-up smell in still air, and the standard remedy is to arrive, open everything and wait, which means the first hour of every visit is spent airing rather than enjoying the house. A unit with a Bluetooth app and timer can run in the connected volume before you arrive, so the house has settled air rather than actively working air by the time you walk in, and that is precisely the difference between a home that smells nice and a home that feels like a suite you checked into. That said, ventilation still comes first, and a house that has been shut needs its windows opened rather than its air perfumed, because scent laid over stale air produces a hybrid that reads as a cover-up. Reeds keep working in the closed rooms while you are away with nobody there to supervise them, which is exactly what an unattended room wants.
What is the single most useful thing to check before deciding?
Your doors, on an ordinary day rather than an imagined one. Walk from your front door to wherever the family sits in the evening on a normal weekday afternoon and count how many doors you actually pass through, then do it again on a Saturday. If the answer is none, you have a large connected volume, most of the house that anybody sees is one continuous body of air, and one machine will cover it with a single object that does not have to be visible. If the answer is two or three, you have a partitioned home, the connected volume is a small share of the house, the machine's advantage nearly disappears and reeds are simply the right answer to your layout rather than a compromise. Then do the arithmetic on the connected part: floor area times ceiling height gives cubic feet, divided by 35.3 gives cubic metres, and the Vaayu is rated at approximately 1000 cubic metres. Count the closed rooms while you are walking, because that number is your reed count. It takes ten minutes, and it is worth more than any recommendation anybody can make without seeing your plan.

Facts verified August 2026: The SOSA Vaayu (₹11,999) is a waterless cold-air nebulising machine covering approximately 1000m³, with Bluetooth app and timer scheduling. It ships with four hotel-inspired waterless blends included in the box, chosen as one of three bundles at purchase: Bundle A - Ritz-Carlton Inspired, Westin Inspired, St. Regis Inspired, 1 Hotels Inspired; Bundle B - Westin Inspired, Shangri-La Inspired, Four Seasons Inspired, Ritz-Carlton Inspired; Bundle C - St. Regis Inspired, W Hotels Inspired, 1 Hotels Inspired, Four Seasons Inspired. Format distinction: the Vaayu and the HVAC systems run waterless nebulising oil, while the separate SOSA Hotel Collection fragrance (15ml ₹299) is water-based and runs in the ultrasonic machines only - Boond (₹899), Sukoon (₹1,899) and Megh (₹3,499). The two fragrance formats are not interchangeable, and the Hotel Collection bottle does not go into a Vaayu. SOSA Aangan (₹25,999) and SOSA Meenar (₹38,500) are HVAC nebulising systems for approximately 8,000-10,000 sq ft and 12,000-18,000 sq ft respectively, ducted into central air-conditioning. Reed diffusers need no power and make no noise: Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799, Mountain Breeze ₹849, Fresh Brew ₹849; 130ml from ₹1,249; duo sets ₹1,498, ₹1,548 and ₹1,598. Scent perception is personal and varies between people in the same room, and coverage figures assume connected air volume rather than a partitioned floor plan. Ventilation, cleaning and air-conditioning come first; fragrance is an addition to a well-kept home and never a substitute for any of them. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or connected to any hotel brand. Made in India, cruelty-free and vegan. A portion of every order supports girl-child education through Nanhi Kali. Ongoing fragrance supply is arranged with SOSA on WhatsApp: +91 96192 18531.
