The spectator writes any secret information on a card. You wrap the card with a sheet of aluminum foil, and you instantly peek at the info. A complete peek right in front of the spectator's eyes! The spectator can even hold the aluminum packet and check that you can't see anything through it! This is X-Ray Peek, a natural, impossible, lab-condition way to secretly peek at any information. Say farewell to your traditional peek wallet; this is flat, lightweight, innocent looking and very deceptive. The ideal EDC peek for any mentalist!
