THE BLURB:
Using this envelope, you can perform the effect of change.
For example, a white paper change into a bill. The greatest
merit of this is that the audience can put something in the
envelope by themselves and pull it out by themselves.

MY COMMENTS:
For those familiar with Ray Piatt's Piatt Envelope, then you
know what this is. Basically, it's a switching envelope.
Honestly, I'm not sure whether Ray actually gets credit for
the idea or not, but I'm fairly certain he gets credited for
marketing this type of envelope first. I could be wrong.
In any case, the basic idea itself is not new.

The difference with these envelopes, which are imported from
Japan, is that there is an adhesive on the end of the flaps
and it's made for sealing. Also, the ends of the envelope
are perforated so you can easily tear it and, more
importantly, let a participant tear it open. This, of
course, means that these envelopes are consumable since you
will be using one up each performance. The package does
come with 20 envelopes. The instructions comprise one side
of a glossy sheet and a magic transposition effect is
included.

Ideally, a mentalist should make his own envelopes so that
you don't have to rely on locating a supply of someone
else's. However, if you're unable or unwilling to do this
(let's face it, I'd prefer to let someone else make my
envelopes, too), then this is a perfectly good utility prop
that you'll find a myriad of uses for. And the price is
fair if you want to stock up on these.
