Birthday card plays a punk rock birthday song non-stop. This song will loop until the batteries die. Transform every occasion into an unforgettable experience with our one-of-a-kind Endless Looping Card. Designed to offer not just one, but two pranks in a single package, this card takes the cake in unconventional gifting. First, the moment the card is opened, it launches into an endless loop of music that lasts for more than 3 hours. Just imagine the smile — and perhaps the playful eye-roll — as the recipient realizes the tunes aren't stopping anytime soon. But wait, there's more! Should the recipient decide to end the auditory experience by tearing open the card, a hidden glitter bomb awaits, providing a second unexpected surprise. This is more than a card; it's a memorable experience packed into an envelope. Whether celebrating a special occasion or just because, our card is the ultimate choice for anyone who enjoys humor, surprises, and a dash of sparkle.
