This trick is awesome. Period.
I do mostly close-up but am called upon from time to time for a
Parlor or Stage magic.
I added this for my bigger gigs and I was very impressed. There are
several methods employed in other products, but the ingenious gimmick is so simple, yet so
surprising on how it all works.
All I can say is that if you're thinking about adding a
larger trick to your set, highly consider this!
