Music Box opens slowly - a key, a lid, then the notes one at a time - which suits fifty years better than confetti.

This is what they get
What to write in a 50th birthday card
“Fifty. We have known each other for thirty-one of them, which explains a great deal about both of us. Happy birthday.”
“You are the only person I would have called at 3am in 1998 and the only one I would call now. Happy 50th.”
“Half a century and still the first person to say yes to a stupid plan. Never change. Happy birthday.”
How it works
What they will see
- Turns the key three times — the mechanism winds and the lid unlocks.
- Lifts the lid: your photo with its caption, then the letter itself.
- Unfolds the little notes one by one, then taps a reply back to you.

Frequently asked questions
What do you write in a 50th birthday card without a joke about age?
Anchor it in time instead. Name the year you met, one thing they did that you still talk about, and one thing you expect from the next decade. A milestone card that counts the friendship lands better than one that counts the candles.
Can other friends add notes?
Yes. Send them the draft link and each one folds a note into the box before you send it. If you want a wall where twenty people each get a line instead, the group-card format is the better fit.
What do they actually receive?
A link that opens a music box: they turn the key, the lid lifts, and your photo, your letter and the notes are inside. No app, no account. Free to build and preview, €3 to send one.
