How it works

Pick one. Name it. Pass it on.

Every card is made to be given away, not kept — so a box of thirty is thirty small moments, not one gift.

1

Pick a card

Thirty designs — mermaids, princesses, rainbows, cats, bears, kawaii treats. Each hides a different message, and the number on the back is the only clue to which one.

2

Write the names

There's a To and From on the back of every card. That's the bit that turns a printed message into something personal, and it takes about four seconds.

3

Give it away

Into a pencil case, a lunchbox, or the front of a birthday present. Then tick it off the tracker sheet so you remember who got which one.

The designs

Cute enough that kids actually want to hand them over.

Six of the thirty, shown here exactly as printed — the rest stay a surprise until the box is open. Every card folds flat and pops open along its die-cut seam.

The bit nobody else does

A record of every kind thing you said.

Each card is numbered, and the box includes a sheet listing what every number says. Kids write down who they gave each one to — so by the end, the sheet is a map of a whole year of friendships.

  • Card 1 — Growing up with you is so much fun.
  • Card 2 — Your kindness lights up my world.
  • Card 3 — Every day with you is a gift.
  • Card 4 — You bring magic and sparkles into my life.
  • Card 5 — You are like a cool rainbow in the sky.

…and twenty-five more we're keeping secret.

Why it works

Kids feel it long before they can say it.

Most children have far more warmth for their friends than they know how to express. Saying "you make me laugh" out loud, to someone's face, at nine years old, is genuinely hard — so a lot of it never gets said at all.

A card does the difficult part. The words are already there; all a child has to do is decide who deserves them. That small act of choosing is where the thinking happens.

“Friendship is the best gift. Share it, cherish it, and let it bloom.”

Every message and every illustration in this box is original. They were written and drawn by a registered psychologist who works with children and teenagers — not licensed from a stock library, and not translated from someone else's set. That's why the language sounds like something a child would actually pass on, rather than something an adult thinks children say.

Schools & practitioners

Buying for a classroom or a clinic?

The cards suit classrooms and clinics — as kindness activities, take-home prompts, or end-of-term notes. Bulk pricing is available, and we can invoice a school or practice directly.

Before you ask

Questions, answered plainly.

How big are the cards?

Roughly 6 × 6 cm folded — about 2.35 inches square. Small enough for a pencil case, a blazer pocket, or the front of a lunchbox.

What age is it for?

Ages 5 to 15. Younger children usually want a hand with the writing; by about eight most are off doing it themselves, and older kids tend to use them for birthdays and end-of-year cards.

Who writes the messages?

Every word and every illustration is original, written and designed by a registered psychologist who works with children and teenagers.

Are all thirty messages different?

Yes — thirty cards, thirty designs, thirty messages. The tracker sheet lists which number says what, so you can pick deliberately or leave it as a surprise.

Can I buy more than one box?

Yes — there's a 2-pack: two complete boxes for $44.95, one to give and one to keep. Two besties can open the same numbered card and compare what it says. Shipping is free and tracked on the 2-pack too.

How much is shipping and how long does it take?

Standard post is free anywhere in Australia, and it's tracked. Express is a flat $3 upgrade, one charge per order however many boxes are in it.

Orders are dispatched from Sydney within 1–2 business days. From there, standard post usually takes 3–7 business days and express 1–3. Full detail on the shipping page.

Can I return it?

Yes — 30 days from delivery for an unopened, unused box, refunded in full once it's back with us. Return postage is yours on a change of mind.

If a box turns up damaged or faulty, send a photo to [email protected] and we'll put it right at no cost to you. None of this limits your rights under the Australian Consumer Law — see the returns page.

Do you ship outside Australia?

No — we post within Australia only. Standard post is free and tracked anywhere in Australia, and express is a flat $3 upgrade.

One email when a new box lands.
