Endless Punk Rock Birthday Card with Hidden Glitter 

This isn't your grandmother's birthday card – it keeps playing the same birthday tune over and over until the battery naturally dies hours later. Once prepared and opened it loops for hours. Closing the card won't help, hiding it won't work, and pleading with it is completely useless!

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

Perfect Occasions For:

• Birthday pranksters seeking unique musical gifts - Stand out from typical birthday cards with this musical prank that combines punk attitude with birthday wishes
• Gift-givers wanting unforgettable birthday surprises - Create a memorable (and slightly annoying) birthday experience with a card that won't stop rocking until the battery dies
• Prank enthusiasts who want glitter bomb protection - Features hidden glitter surprise that activates if the recipient tries to destroy the card or remove the battery to stop the music
