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
- If the recipient tries to break it we hid glitter inside the card
*Plain white envelope included

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.
How do I activate the card?
We suggest inserting the card into the envelope first the remove the instructional tab from the spine. The moment your recipient opens the card, the song (or sound, depending on your design) starts playing automatically and won't stop until the battery dies or it's broken.
How do I stop the song?
Once activated there is no off switch. The song plays until the battery dies. Attempting to destroy the card triggers the hidden glitter (or in some cases the glitter is found when the pull strip is removed). That's the prank.
Does the card come with a Glitter Envelope
No. All cards ship with a plain white envelope. The glitter is already built inside the card itself, either hidden inside waiting to be unleashed or behind a pull-strip reveal. If you want the full glitter ambush on the outside too, we sell Glitter Trap Envelopes separately.
