Endless Birthday Screamer Musical Prank Card with Glitter Surprise

This absolutely diabolical birthday screamer card transforms any birthday into a psychological horror experience that plays out over hours. What looks like an edgy birthday greeting becomes a jump-scare marathon featuring random loud screams every 30 seconds that your victim will never see coming.

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, every 30 seconds, 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
