I certainly agree with all the other reviewers that this a fantastic opening effect. The guys at
our round table magic meeting were amazed that it was so visual and deceptive. One reviewer pointed
out that when removing the folder from a jacket pocket, the gimmick can become slightly misaligned.
The fix is easy. I used a very little roughing fluid on the back of the case gimmick and the front
of the folder, which cause enough friction that there is no slippage yet it doesn't interfere with
effect. Highly recommended.
