This is a very clever gimmick!!! I created a new routine with it that's not on the video.I find a match of the gimmick card from a regular deck. I cut the corner off the card. Then I palm the cut off corner. When I tear off the corner from the gimmick card, I show the palmed torn corner. I place the card into a mailing envelope. I show that the envelope is empty first. I then seal the envelope. I then make the torn corner disappear and act like I sprinkled the torn corner into the sealed envelope. Then I open the envelope and produce the restored card. I like this routine I created because with this Gimmick as you may know the crease can be easily seen. So I like the fact the envelope conceals the card. Hope you like my new routine....
