You show the box completely empty in the beginning and then give it to the spectator to hold. You never touch the box again.
Have them sign a playing card and lose it in the deck. The card vanishes. They push the box open themselves and, located inside, there is one card. You dump it into your hand and unfold it. It is their signed card!
All accomplished with an organic, everyday object.
Easy to do.
Fits easily into your pocket.
Gimmick can be built in less than a minute.
Bonus effect included, whereby the empty match box becomes magically filled with matches!
