Endless Happy Birthday Musical Prank Card with Hidden Glitter

Forget boring birthday cards. The Endless Birthday with Glitter card from Joker Greeting is a chaotic twist on the classic birthday wish. It starts innocent enough—open the card to sign your message and close it like normal. But once you pull the plastic tab and hand it off, the fun begins. It’s the kind of gift that says “I love you” and “good luck sleeping” at the same time.

How the Endless Musical Card Works 

1. Open the card to test the sound; sign it, close the card to stop the sample
2. Insert the card into the envelope; pull the tab from the spine to arm it.
3. Once the recipient opens the card it will start and loop non-stop even if they close the card; it will run until the battery dies; hours later
4. If the recipient tries to break it we hid glitter inside the card

*Plain white envelope included in all cards

Perfect Occasions

• Big birthdays – Turn a 30th, 40th, or 50th into pure birthday chaos.
• Office pranks – Add some fun (and noise) to the workplace birthday culture.
• Sibling rivalry – Give your brother or sister a birthday memory that lasts (way too long).
• Friends who love (or hate) glitter – Either way, you win.
• People who say “don’t get me anything” – Surprise! You got them everything.
