A kid’s birthday envelope with the whole family singing in it.

A birthday envelope they can open again and again. Write the letter, add the photos, and a film if there’s one to send, so they can hear you say it. Pay once and send the link. They open it on their screen, like the real thing.

Kid’s birthday envelope: what goes inside

A letter

Addressed to them, in words they can read, or that you’ll read aloud. What they did this year that made you proud.

Dear Ada, This year you learned to ride a bike and to whistle. Mostly the whistling.

A postcard

A photo from last birthday, and one from this morning. They like seeing how much they’ve grown.

Five. Candles: five. Cake on face: most of it.

A film

Grandparents singing, cousins shouting, the dog barking at the end. Play it at the party.

1:40 · Happy birthday, in four accents

How it works

Fill the envelope with a letter, postcards and a film — any mix, up to ten pieces, and one price for the whole envelope by what's inside. Pay once, by card. Send the link now, or keep it sealed until the day: no app to install, it opens on any phone, and it's kept for good.

Kid’s birthday envelope questions

Can they open it on their own tablet?

Yes. It opens in the browser, so any phone or tablet works, with no app and no account. Small ones might want a grown-up to open it with them.

Can they open it again next year?

The link lasts for good, so they can open it as often as they like. The film is kept for a year after the first opening, so save a copy if it’s a keeper.

How much does it cost?

$1.29 for letters and postcards, $5 with a film. One price for the whole envelope, up to ten pieces, paid once by card through Stripe. No subscription.

Do they need an app?

No. One link, opened in the browser on any phone, tablet or computer. They tap the seal and the envelope opens.

When should I send it?

Whenever you like. Send the link straight away, or send it now and set the day and time it opens — until then they’ll see the sealed envelope and a countdown.

Can I change it after I’ve paid?

Until they open it, yes. Sign in with the email you paid with and change what’s inside; the link stays the same. You can’t add anything that costs more than you paid, and once they’ve opened it, it stays as it is.

How long does it last?

For good. They can open it as many times as they like. A film is kept for a year after it’s first opened, and they can save their own copy.
