The Rather Marvellous Notebook for Equations, Ideas and Idle Thoughts
Right then. If you've ever felt the urge to scribble down a brilliant mathematical insight, sketch the next big thing, or simply record what you had for lunch using only differential calculus, we may have just the thing. This is a properly handsome A5 notebook, handmade in the UK with more care than we typically apply to, well, anything really.
Why Choose Our Mathematics Notebook
The Covers Are Rather Splendid: Featuring the equations of Srinivasa Ramanujan layered with the work of Newton, Pythagoras and other giants of mathematics. It's the sort of thing that looks gorgeous on your desk and possibly makes you appear cleverer than you actually are.
Paper That Actually Works With Your Pen: We've used 100 gsm fountain-pen-friendly paper because we discovered, after much bumbling about, that cheap paper and nice pens are rather at odds with one another.
It Opens Completely Flat: Revolutionary, we know. But there's something wonderfully satisfying about a notebook that doesn't try to snap shut on your thoughts mid-sentence.
Built to Last: Hardcover binding means this will survive the rigours of your bag, your desk and that period where you inevitably use it as a coaster.

Whether you're solving Fermat's Last Theorem, sketching your path to mathematical glory, or simply capturing the occasionally coherent thoughts that drift through your day, this notebook is rather good at standing by you. It also makes a splendid gift for someone who appreciates both mathematics and a touch of understated sophistication.
Treat yourself or someone special to a notebook that's as thoughtfully made as it is beautifully presented.
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.
