Endless Birthday with No Glitter
Endless Blue Birthday Musical Greeting Card – Hilarious Prank That Plays for Hours
Celebrate birthdays with a side of chaos. The Endless Blue Birthday Musical Greeting Card by Joker Greeting is more than just a card — it’s a non-stop party. Designed to look like a normal birthday card, it plays a cheerful birthday tune when opened… but here’s the twist: once the activation tab is removed, it loops the music endlessly until the battery dies
How the Endless Musical Card Works
- Open the card to test the sound; sign it, close the card to stop the sample
- Insert the card into the envelope; pull the tab from the spine to arm it.
- 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
- This card has no glitter inside when it is broken like our other cards
*Plain white envelope included in all cards
Perfect For:
-
Gag gift lovers who want their card to really be remembered
-
Birthdays for friends, family, coworkers — all ages welcome
-
Office parties, birthday pranks, or anyone who “loves” surprises
-
Those tired of boring greeting cards and ready for chaos
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.
