Endless Thank You Grandparent Card with Glitter
This thank you card for grandparents plays a piano version of "The Entertainer" nonstop until the battery dies
It opens like a sweet thank you to Grandma or Grandpa — and then the piano kicks in. A cheerful, ragtime-style rendition of "The Entertainer" they'll recognize instantly, playing on a loop that does not stop. Close the card and it keeps going. Set it on the counter and it keeps going. It loops nonstop, even when closed, for hours until the battery finally dies. You can open it to test the sound, sign it, and get it ready first; it only arms once you pull the tab, so there's no rush and no surprises on your end.
That's the whole joke. It's a genuine thank you wrapped around a tune that'll have their toes tapping whether they like it or not — and it keeps going long enough to earn a "what did you send me?!" phone call. Works for Grandma or Grandpa, any time of year you want to say thanks and keep them on their toes. It's the kind of gift they'll actually remember.
How the Endless Musical Card Works
- Open the card to test the sound, sign it, then close the card to stop the sample.
- Insert the card into the envelope and pull the tab from the spine to arm it.
- Once the recipient opens the card, it loops non-stop — even if they close it — and plays for hours, until the battery dies.
- When they finally give up and try to pull the battery to stop it, a hidden glitter trap spills everywhere.
Plain white envelope included in all cards
Frequently Asked Questions
Can I sign the card before it activates?
Yes. You can safely sign the card and it will play one-time. Close the card and it will stop.
How long does the song play?
Once activated, the card plays continuously for 3 to 6 hours until the internal battery dies. There is no off switch. Please note; batteries are like a sponge so if they open it again you'll get more music.
Does the card come with a Glitter Envelope
No. All cards ship with a plain white envelope. The glitter is already built inside the card itself, either hidden inside waiting to be unleashed or behind a pull-strip reveal. If you want the full glitter ambush on the outside too, we sell Glitter Trap Envelopes separately.
How do I stop the song?
Once activated there is no off switch. The song plays until the battery dies. Attempting to destroy the card triggers the hidden glitter (or in some cases the glitter is found when the pull strip is removed). That's the prank.
How do I activate the card?
We suggest inserting the card into the envelope first the remove the instructional tab from the spine. The moment your recipient opens the card, the song (or sound, depending on your design) starts playing automatically and won't stop until the battery dies or it's broken.
