A Gloriously Reusable Mug for Life’s Hot Messes
Say hello to your new favourite beverage-bearing companion. The Sunshine Stinky Travel Mug is fabulously reusable, delightfully stylish, and just quirky enough to raise eyebrows while queueing for your oat flat white. Inspired by a rather misbehaved character from a beloved Moomin tale, it’s here to help you sip sustainably, whether commuting, procrastinating or audibly sighing through another Zoom faux-meeting.
Why Choose Our Travel Mug?
- Biodegradable Build: Crafted from renewable PLA. It looks like plastic, behaves like a saint, and pairs marvellously with a recyclable silicone sleeve that won’t slip through your slightly frazzled hands.
- Generously Practical Size: A hearty 450 ml capacity — perfect for everything from artisan lattes to the sort of tea you forgot you brewed half an hour ago.
- Nostalgic Whimsy: Features one glaringly glorious nod to your Moomin-filled youth, giving your morning routine a charming little wink of mischief.
Product Details:
- Materials: Biodegradable PLA and food-grade silicone.
- Capacity: 450 ml.
- Packaging: Arrives in an eco-friendly carton — pleasing to both the planet and your cat, oddly enough.
This isn’t just a cup. It’s a gloriously grumpy eco-hero disguised as a travel mug. Snap one up now and join the rather fabulous crowd of sustainable sippers who know good style doesn’t end with your socks.
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.
