Celebrate birthdays with a twist of humor and an endless melody! Our white birthday card is not just any ordinary greeting card. It's a bundle of joy, laughter, and a bit of mischief. Designed to play the cheerful 'Happy Birthday' tune non-stop for at least 3 hours, it's the perfect way to add an unforgettable touch to the special day. The card is safe to open, sign, and test the music, ensuring a surprise-free setup. But the real fun begins when your recipient discovers the card's relentless spirit. If they attempt to break the card in hopes of stopping the music, they'll be greeted with a burst of chunky glitter – a playful glitter bomb that adds to the amusement. This card is perfect for those who appreciate a good laugh and a memorable celebration. It's easy to use: simply sign the card, place it inside the envelope, then pull the tab to activate the music. And for those who like a personal touch, we offer personalization options at our Joker ship. Give the gift of endless music and laughter with our unique white birthday card.
