Boozy Gourmet Marshmallow Advent Calendar (18+)
Our best-selling boozy gourmet marshmallow Advent calendar is back - featuring six boozy inspired flavours. Behind each door, you’ll find a delicious piece of handmade gourmet marshmallow in a selection of sumptuous boozy flavours.
That’s 25 deliciously gooey pieces of heaven to savour this Christmas and a great motivator for getting out of bed on those cold Winter mornings.
On the reverse of each door, you’ll find out which flavour you’ll be enjoying that day, as well as either a festive joke, fun fact or exclusive online discount code to be redeemed on our website.
Our Boozy Gourmet Marshmallow Advent Calendar features an incredible six alternating flavours from our Boozy-Edition range, which include: Raspberry & Prosecco, Peach Bellini, Elderflower & Gin, Violet Gin, Passion Fruit Martini and Pina Colada.
The larger central door for Christmas Day includes a milk chocolate enrobed raspberry & prosecco marshmallow bar - made using our boozy raspberry prosecco recipe marshmallow and finest Belgian milk chocolate.
As an optional extra, you can also choose to add on one of our awesome marshmallow toasting kits, so that you can toast each marshmallow to gooey perfection. Simply light the gel with a match or similar to ignite and drop the lid back on to extinguish the flame and repeat. Our marshmallow toaster is non-toxic, smokeless and odourless and full safety instructions are included.
The toasting kit add-on includes: 1 x marshmallow toaster, 1 x instruction guide, 24 x bamboo skewers and will last for the duration of the calendar.
As featured on: ITV’s ‘This Morning’ and in ‘Metro’, ‘Heatworld’, ‘Good Housekeeping’, ‘The Telegraph’, ‘Popsugar’, ‘Stylist’, ‘The Sun’ and many more.

A Note About Delivery Times
Each of our products is lovingly handmade in small batches by our team of artisans in our Lincolnshire kitchens. Staying true to our “Naked” ethos, we avoid using artificial preservatives, which means our produce is crafted fresh and in limited quantities.
To ensure both quality and freshness—especially during the festive season—we cannot produce large volumes too far in advance. As a result, some festive items may be prepared and dispatched at slightly different intervals than our usual schedule.
Please rest assured that your order will be sent out at the very earliest opportunity. We truly appreciate your patience and understanding as you support our small business.
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
Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?
We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect.
Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience. Every object tells a story, and every purchase supports an independent brand doing things differently.
This is just the beginning. But enough about us — step inside, explore our world, and see what catches your imagination.
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.
