A secret weapon for magicians and mentalists. This is one of the most devious and ordinary-looking props a magician and mentalist can use. The concept of multiple outs is a powerful weapon when used in a mental effect. Books have been written on the subject and hundreds of props have been invented to produce the desired results. The Piatt Envelope is among the best and fairest methods ever invented for this purpose. The envelopes are standard looking coin and invitation envelopes. The handling of the envelopes is direct. The envelopes are gaffed and are large enough to hold a playing card. Miracles can seemingly be accomplished with this device. You get two specially manufactured and assembled envelopes. One looks like a 4.25 x 2.5 inch Kraft coin envelope and the other is a 5.25 x 3.5 inch white invitation envelope. Includes photo-illustrated instructions and ideas for many uses.
