Endless Birthday Cake Punk Rock Musical Prank Card with Hidden Glitter

This rebellious birthday card transforms any birthday into an endless punk rock that plays for hours. What looks like a sweet birthday greeting becomes a 5-10 hour musical rebellion featuring an annoying punk rock birthday song that your recipient will never forget (no matter how hard they try).

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
