Endless Mariachi Birthday Musical Prank Card with Hidden Glitter

This delightfully festive mariachi birthday card transforms any birthday into an authentic Mexican celebration that plays for hours. What looks like a charming birthday greeting becomes a 5-10 hour mariachi serenade featuring traditional Mexican music that your recipient will never forget.

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
