Rosso Car Diffuser with Refills
Pickup currently not available
A Rather Good Way to Make Your Car Smell Marvellous
If your car ™s interior feels more 'forgotten lunchbox' than 'luxury retreat', allow us to introduce the Rosso Car Diffuser. A gloriously uplifting blend of juicy grapes, ripe berries, delicate violets and magnolias, all tied together with a woody whisper of birch. It ™s the sort of smell that makes you sigh, pause and forget you ™re in traffic behind a cement mixer.
Why Choose Our Rosso Car Diffuser?
Fragrance That Lasts: Keeps your car fabulously scented for weeks, without the usual mysterious dangling tree.
Utterly Simple to Refill: Choose between fragrance oil or replacement capsules. Either way, you ™re refreshed in no time, with minimal faff.
Rather Fetching Design: Not to be smug, but this diffuser looks very nice perched on a vent. Subtle, stylish, and absolutely not trying too hard.
Product Details:
Scent Profile: A fruity-floral ensemble with violet, magnolia and birch notes
Car Freshener Type: Passive diffuser with refillable capsule
Refill Options: Add fragrance oil via dropper or pop in a pre-scented capsule
Duration: Approximately 4 glorious weeks of fragrance per fill
Don't Miss Out
Turns out a properly handsome car scent does exist. Grab yours before someone else ™s commute smells better than yours.
SHIPPING + RETURNS
THE RATHER IMPORTANT BITS
This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.
SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.
Some are brilliant at international shipping, others prefer to keep things closer to home.
At checkout, you'll see exactly where this particular brand can send your goodies.
We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!
RETURNS
You have 14 days to return items.
Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!
🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.
Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!
The brands we work with all have a chat option, and they love to chat!
PAYMENT
We're frightfully modern and accept all the usual suspects:
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay
SECURE AS HOUSES
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!
All prices in lovely British pounds £ GBP, though international chaps will see converted prices.
Any payment pickle? We're here to help sort things out! Contact us

We are Sostter
We met as children. Grew up a few streets apart. Built dens, rode bikes, and eventually — built Sostter.
It started with a shared love of objects that meant something…things with a past, or at least a purpose.
Now, Sostter is our grown-up version of a treasure hunt: a space where design meets storytelling.
We curate independent brands, one-of-a-kind finds, and everyday essentials with character.
Giving Back
We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.
