These cards are the perfect method of using cards in PK effects.

Loads of effects are possible using this card. It will add an extra dimension to your coin matrix effect!

You'll probably find loads of uses for this. Sit down with a PK magnet, a shim card and half an hour and you'll be working all kinds of mind blowing magic!

Think the spectator will suss you? will they heck! It's practically undetectable! 

It contains a very thin steel shim inside, which causes the card to be attracted to magnets. (The card is not actually magnetic)

Product is one card in clamshell packaging.
