A Rather Splendid Mug That Actually Works
Look, we're not going to pretend this is anything other than what it is: a beautifully crafted ceramic mug designed by people who actually care about the objects they make. The sort of thing that makes your morning coffee taste fractionally better, purely because it feels marvellous in your hands.
Why Choose Our Sienna Mug
Properly Handmade: Each mug is individually crafted, so yours is genuinely one of a kind. No two are quite identical, which is either charming or maddening depending on your disposition.
Food-Safe Glazing: High-grade, food-safe glaze means you can drink from it without existential worry.
Dishwasher Safe: Because life is too short for hand-washing everything.
Gorgeous Stoneware: Made from quality stoneware clay that's built to last rather longer than most friendships.
Perfect Size: Neither absurdly large nor insulting in its smallness, just rather good proportions for daily use.
Product Details
Dimensions: 3.9 inches diameter by 1.5 inches height
Material: High-quality stoneware clay
Finish: Food-safe, high-grade ceramic glaze
Care: Dishwasher safe
This is the sort of mug people notice. The sort you'll find yourself reaching for first thing, day after day. Quite the showstopper, really.
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!
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 Have Lots More Like This.........
Hello, 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.
