Dear friend, at the tideline I met a hermit crab called Bram. He carries his house with him — just like me! But Bram is looking for a bigger one. Where do you think he'd feel at home? Waar zou Bram zich thuis voelen, denk je?

Made & mailed · Ages 6+ · EN + NL
Eyo carries a tiny studio on his back — pens, ink, paper, a very small printing press. Every two months he travels to a new world and mails your child a box of things he made: a journal, a letter, a new friend to collect. And whatever your child makes back, Eyo answers.
Goed werk haast zich niet. — Good work never hurries.
Launching autumn 2026. Fits through every Dutch letterbox.
Season One is limited — because Eyo writes back to every one of them by hand. Join the list and you'll be first to know when the doors open.
Every box holds a reply card your child draws and writes on. Eyo reads it — and his next letter remembers what they made. A real exchange, not just content.
Six destinations, six friends, one fold-out map that grows every box. By season's end your child holds a whole world they made themselves.
Every letter, journal and prompt is written natively in English and Dutch — made in the Netherlands for Dutch and international families alike.
How it works
The exchange from Eyo's first two boxes. Notice what happens two months later.
Dear friend, at the tideline I met a hermit crab called Bram. He carries his house with him — just like me! But Bram is looking for a bigger one. Where do you think he'd feel at home? Waar zou Bram zich thuis voelen, denk je?

Dear Eyo, I gave Bram a home behind the big rock. It has a garden. Do turtles ever get seasick? — Fleur, 7
Bram LOVES his home behind the big rock — he asked me to tell you the garden is his favourite part. And no, turtles never get seasick. We just get sleepy. Now, about the hedgehog I met in the forest… Bram is dol op zijn huisje achter de grote rots!

"He remembered me." That's the moment we make, six times a year.
Why only 100
Eyo could send a thousand boxes. He could not read a thousand letters. So he doesn't try.
I have thought about this carefully, which is the only way I think about anything.
If I take on too many friends, I will start to write the same letter twice. And a letter that could have been written to anyone is not really a letter at all.
So: one hundred friends this season. I will know all of your names. Honderd vrienden. Ik zal al jullie namen kennen.
— Eyo 🐢
Your child's card is opened and read — not scanned, not automated. What they wrote shapes what arrives next.
Printed, cut, folded and packed in a small studio in the Netherlands. One hundred boxes is what two hands can do properly.
Your child's copy carries its own number — No. 47 of 100 — written on the journal's first page. There will never be another Season One.
Join Season One and your child's number, and their rate, are held for every season that follows. Seasons close; founders don't.
Season One
Eyo makes and mails from a new destination every two months. Each box brings a collectible friend-card and a stamp for your child's fold-out map of Eyo's World.
Box 1 · Autumn
aan zee
Box 2
in het bos
Box 3
in de sneeuw
Box 4
in de ruimte
Box 5
in de geheime tuin
Box 6
diep in de zee
The map is the keepsake. Box 1 includes Eyo's World — a fold-out map with a slot for every friend-card and every travel stamp. Six boxes, one finished world your child completes themselves.
Inside every box
Every box follows the same six-part rhythm, and everything fits flat through a Dutch letterbox.
A journal, a letter-writing set, a keepsake your child fills with their own words and keeps long after the box is recycled. Box 1: Eyo's Seaside journal — 28 pages, prompted-but-open, in two languages, and hand-numbered No. __ of 100 on the first page.
Small tools, chosen to match the destination.
Little stickers for big imaginations.
Something your child makes and mails to someone they love. Grandparents are perfect recipients.
The story of his journey, a new friend-card, and a card for your child to write back to Eyo.
What's inside, how the reply loop works, and one good conversation to have together.
Letterbox-proof: every box is designed under 3.2 cm — no missed deliveries, no trips to the pick-up point.

Good questions
Season One · 100 places
Eyo is still making the first boxes. Leave your name and we'll write to you the day Season One opens — before anyone else, and before the hundred places are spoken for.
The small print, kindly
When you join the Studio Eyo waitlist, we collect your name, your email address, and — only if you choose to share it — your child's age. We ask for these so we can write to you when Season One opens and share the occasional update about Studio Eyo. Nothing more.
We do this only because you've given your consent by ticking the box on the signup form. Your details are stored securely in our email tool, and are never sold or shared with anyone else.
You stay in control. Every email we send includes an unsubscribe link, and you can ask to see what we hold about you, or have it deleted entirely, at any time — just email [your email]. We keep your details only until you unsubscribe, or until the launch season is over.
