Splendid Fish Birthday Cards That Actually Make People Smile
Look, we'll be honest. Most birthday cards are rather forgettable affairs that end up in a drawer somewhere between old receipts and that instruction manual you'll never read. These ones, however, are rather different. Gorgeously colourful fish designs that manage to be both utterly fetching and genuinely funny, printed on proper quality card that feels marvellous in your hands.
Why Choose Our Birthday Cards
Beautifully Crafted Quality: Each card is printed on substantial 280gsm card stock, the sort of thing that makes you think someone actually cared when they're opening it.
Thoughtfully Made: We've chosen vegetable inks and sustainable forest sources because, well, if you're going to send something into the world, it might as well not feel guilty about it.
Delightfully Stylish Design: Quirky fish illustrations that work for fish enthusiasts, aquarium lovers, or anyone who simply appreciates something a bit different from the usual birthday fare.
Perfectly Blank Inside: Room for your own message, whether that's heartfelt, hilarious, or somewhere gloriously in between.
Properly Packaged: Comes wrapped in recyclable sleeves because the whole sustainable thing extends to how it arrives at your door.
Product Details
Card Size: 120mm square, a rather good size that sits nicely on a shelf.
Materials: 280gsm card printed with vegetable inks from sustainably managed forests.
Format: Blank inside for your own message.
Packaging: Recyclable cardboard sleeve.
These cards have a way of becoming the sort of thing people keep rather than bin, which we rather think is the whole point of a birthday card, isn't it.
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!

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.
