Magic Tricks

This is an excellent effect that is as easy as a bill switch and VERY visual! I've gotten great reactions with this. The Tyvek paper it's made of is tough and will resist water and much folding; but with every fold and unfold of the natural process of doing this trick, the integrity of the paper is slightly diminished. Don't get me wrong, it's tough. It will last you many weeks, if not multiple months, of use. Will it last years? Not likely if you do this multiple times, daily; despite the tough nature of the paper.
This is visual. It makes more sense than a bill switch/change. It gets great reactions and you can hand out the twenty at the end for spending, if you'd like. For $20, though, (the current price of the item at the time of the writing of this review), I think they should provide two. I bought my first ones at a Gregory Wilson lecture and paid less than half that for two of them. I bought one from Penguin as a backup. This is a quality made gimmick and a fantastic illusion that is easily executed. It's just slightly overpriced, (in my opinion); but that may be due to the printing and paper cost involved in making it.
