Endless Screamer Birthday Card with Glitter

It doesn't sing. It screams. Every 30 seconds. For hours.

Most musical cards play a song. This one screams every 30 seconds. It takes a pause and Thirty seconds later, another one. And another. For hours, until the battery dies. It's the only card in our catalog designed not to entertain, but to keep the recipient on edge.

The cover is a striking black-and-white "Happy Birthday" in dripping paint-style lettering — and the art sets the tone before they ever open it. They'll know something's off. Then they open it. And they wait. And then they scream. The recipient will absolutely text you "WHAT did you send me?!" — which might actually start a conversation if you haven't talked in a while. Unlike a paper card that gets read once and forgotten, this one keeps haunting them for hours. For horror fans, prank veterans, and anyone whose birthday could use a little jump-scare energy.

A note on who this card is for: it's loud and designed to startle. We'd skip it for kids, anyone easily spooked, and anyone with anxiety or heart conditions. For everyone else who can take a scare — it's our most committed prank card.

How the Endless Musical Card Works

1. Open the card to test the sound, sign it, then close the card to stop the sample.
2. Insert the card into the envelope and pull the tab from the spine to arm it.
3. Once they open the card, a loud scream plays every 30 seconds — even if they close it — and keeps going for hours, until the battery dies.
4. If they try to break the card to stop the screaming, a hidden glitter trap is waiting inside.

Ideas for When to Use It

• For October birthdays — Halloween-week birthdays were practically designed for this card. Scary-movie season, scary card, perfect alignment.
• For the horror fan — they collect the genre. Now they're in it.
• For the prank veteran — the friend who's already received every prank card you've ever sent. This one resets the bar.
• Office birthdays — a scream every 30 seconds from a desk drawer is the kind of workplace event that becomes a long-running story.
• For someone who scares easily — affectionately. Maybe send a warning text first. Or don't.
