Vanishing Deck - Bicycle

So, you've got a deck of cards. Show it off, slide it into this black card case, do a little magic gesture, and suddenly the deck's gone. Just an empty case left in your hands. No mirrors, no trapdoors.

It's one of those tricks that just works. The plastic's decent enough not to embarrass you in the middle of a performance. There are cheaper versions out there, but they're about as reliable as a chocolate teapot. This one's a keeper.
