Magic Tricks

Four stars because this does what it's supposed to do: it switches bills, cards, etc. and it does it well and it does it while the spectator is holding the envelope. So why not five stars? Well, because the gimmick is easily exposed if the lighting is bright. And, as others have noted, for the price they could have provided more than two envelopes. They're paper, after all, and durability is a question mark. The instructions are good, and this is definitely something that can be a stunner with the right effect.
