This isn't a trick; nor is it a set of instructions that teach you 100 different variations on the
same thing. This is something for workers; a clear force bag. Without going into method, you can
have hundreds of cards, coins, dice... ANYTHING in plain sight and have a spectator take THE one YOU
want them too... INCREDIBLY fairly.
This bag is a VERY, VERY versatile prop; there are
HUNDREDS of effects possible, and the amount of creative potential this has is UNLIMITED. In all
seriousness, you are more likely to come up with an original effect if you have one of these than
you would be with ANY other prop in magic (or I think so, anyway).
HIGHLY recommended.
