SpyCat Wallet by Mark Stone

Everyday use wallets have become smaller and smaller over the years because we have changed from a mostly cash society to a mostly 'plastic money' society. This means a typical wallet today only needs to hold a few credit cards and a driver's license and thus it is much smaller than the wallets of days past. This completely normal-looking peek wallet is small and thin. Purchase it for about $10 and then modify it to turn it into a deceptive peek wallet in a few minutes.

There are no mirrors and no magnets in this wallet. Mirrors complicate the peeking of words and numbers and thus require you to peek longer which can give away the method. Magnets can be noisy. This well-thought-out design avoids all of these problems. The PDF gives detailed instructions on where to purchase the wallet and how to gimmick it. The video demonstrates how the wallet is handled both from the spectator's and performer's view.
