Taking off the seal of a deck of cards, you have the spectator thoroughly examine it, then ask them to select and sign a card. You lose their card in the deck and place it back inside the box, resealing the flap of the box tightly. With not a single move, the seal INSTANTLY vanishes as it jumps inside the box with one mission: to hunt down the spectator's signed selection.
Without hesitation, you take the cards out of the deck again, leafing through when suddenly - BOOM- On the back of ONE card is the seal. You slowly turn it over revealing it is the spectator's signed card,but it doesn't end there. Simply shake the card and the seal disappears back home, reappearing on the deck of cards from whence it came. Sealing the deck up again, your spectator is free to keep the card as a souvenir.

Sealed Up is a trick you should already be incorporating into your routines. It's incredibly simple and versatile. With only one effect you get two separate vanishes, a trick, and a souvenir. It's simply a must-have for any magician aiming for a spectacularly diverse repertoire.
