I've constructed MO envelopes. I've bought MO wallets. But Number 4 Envelope is the best solution if
you need four outs. The design is perfect. It looks like an ordinary envelope, and your spectators
will never suspect that is gaffed. In the past, I've used a Wow wallet for performing Cassidy's
Chronologue. It's great and uses the same principle as the Number 4 Envelope, but when you see the
instructional video, you'll see why the envelope is superior.
You will find many uses for
this. (I'm using it with a Crossroads Deck.) It's one of the best utilities in a long time. Just get
it!
