Fabulously Hot or Impressively Cold, No Fuss

Whether you’re muddling through a morning commute or enjoying a saunter in the park, this delightfully stylish thermos ensures your drink stays just right. And yes, it features a guinea pig. Quite right too. Because hydration is serious business, but it does no harm to look utterly fetching while doing it.

Why Choose Our Light Green Stainless Steel Guinea Pig Thermos 350ml?

Double Walled Stainless Steel Design: Keeps hot drinks marvellously warm for up to 6 hours, and cold ones fabulously frosty for 12. One could say it's rather good at multitasking.

Leakproof Cap: Pop it in your tote, backpack, or satchel with reckless confidence. No leaks. No damp disasters. Just dry, smug dignity.

Eco Friendly and Gift Ready: Arrives in a recycled cardboard tube that practically begs to be given as a present. Ribbon optional, applause inevitable.

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.
