You'll have to practice this for quite some time to get it to look natural.
The main
gimmicked envelope is simple, but loading it is not easy and smooth.
Lastly, it is
impossible to end clean. Spectators can examine the red and black envelopes, but the white reveal
envelope can not can be examined. It doesn't come with an additional white ungimmicked envelope to
do a switch.
Way too many "I hope this goes right" thoughts will permeate your
presentation.
If you like arts and crafts (to make an ungimmcked white envelope), and a
clunky loading method.
Going into a drawer until I get around to making an examinable white
envelope.
Very disappointed with a trick that is WAY overpriced.
