Endless Farting Glitter Envelope

Turn Any Card You Send Into a Fart Bomb

Most envelopes are just background. This one is the gift. It's a 5×7 musical glitter envelope that lets you weaponize any greeting card you already own — including ours. Slip a card in, seal it, arm it, and you're done. The second the recipient pulls the "Let It Rip" strip, glitter tumbles everywhere — and when they lift the flap, fart sounds kick in and loop for hours, until the battery dies. Most cards never reach this level of commitment.

It's built to pair with our endless musical cards — drop a Happy Birthday card inside and they get a card playing one song and an envelope playing farts at the same time. But it works with any standard 5×7 card: birthdays, Father's Day, anniversaries, thank-yous, just-because. Wherever a regular envelope would do, this one does considerably more.

How the Endless Musical Envelope Works

1. Open the flap once to test the fart sound — this is safe mode, it won't fully arm yet. Slip your 5×7 card inside (pull its tab too if it's one of our endless cards).
2. Peel the adhesive strip, fold the flap, and press to seal — self-sealing, no licking.
3. Pull the arming tab on top, then hand it over or mail it like any envelope (needs a little extra postage).
4. When they pull the "Let It Rip" strip, glitter tumbles out — and the moment they lift the flap, the farts begin, looping for hours until the battery dies.

Great For

• Pairing with a Joker Greeting endless card — one song from the card, a fart loop from the envelope, at the same time. Maximum commitment.
• Dad — Father's Day, his birthday, or any day fart humor lands (which, honestly, is most of them).
• Any birthday — works with any birthday card, ours or not, and makes the standard one unforgettable.
• Anniversaries, thank-yous, congratulations — wherever a polite card is expected, this one delivers something else.
• The card you already bought — no need to toss the one you picked; this upgrades it into a prank.
