SHIMMED BICYCLE CARDS
This is a Bicycle Card with a magnetic steel shim inserted between the layers of the card. This will attract (or be attracted by) a magnet or magnetized object. The shimmed card is the same thickness as a regular Bicycle Card, and can be handled by a spectator without arousing suspicion. The shimmed card is normally used with magnetized coins, available from your local magic dealer. Supplied with instructions for various effects.
