Fabulously Functional with a Hint of Flair

If you're the sort of discerning human who believes your pocket deserves more than a tatty bit of faux leather, may we gently present this rather marvellous card holder — crafted from genuine slate stone and imbued with a kind of rugged sophistication that says, "Yes, I do have my life moderately together."

Why Choose Our Slate Stone RFID Blocking Card Holder?

Beautifully Crafted: Each piece is hewn from natural slate stone, meaning no two holders are quite the same. It’s like carrying a pocket-sized sculpture — just rather more useful.
Eco Considerate: Produced using solar-powered wizardry and wrapped up in recyclable packaging. The planet nods approvingly.
RFID Blocking: Protects up to 12 cards from invisible skulduggery, saving you from those mysterious tap-and-go mishaps.
Two Stylish Options: Like your cash with a clip or prefer a sleeker silhouette? Choose the one that suits your vibe.
Gloriously Made: Assembled by mindful makers who believe a card holder should be lasting, lovely, and just a smidge conversation-starting.

Product Details:

Capacity: Holds up to 12 cards
Material: Natural slate stone
Added Feature: RFID security layer
Packaging: Fully recyclable options
Extras: Available with or without money clip

This card holder makes for a thoughtfully dapper upgrade — or, quite frankly, a rather good gift. Add one to your cart and slip a bit of refined ruggedness into your daily carry.

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!

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

Sostter independent brands marketplace — discover extraordinary makers from around the world

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. Explore our British makers, discover sustainable brands, browse women-led businesses, find the perfect gift for her, or simply wander through our new arrivals and see what finds you.

This is just the beginning. But enough about us — read all about us, or step inside and see what catches your imagination.

A Curated Marketplace for Independent Ethical Brands

Discover our world of independent brands, conscious design, and purposeful creativity — all in one place.

Sostter is more than a marketplace. We're here to inspire a more thoughtful way to shop — one that celebrates the makers, the dreamers, and the independent brands doing things properly. Every brand on Sostter has been individually vetted for its originality, quality, and values. From sustainable fashion and ethical homeware to handmade jewellery and design-led gifts — all brought together in one considered space. Browse by location, by purpose, or simply wander and see what finds you. Want to sell with us? We'd love to hear from you.
