Love these envelopes (as with everything of Richard's)! As a fellow mentalist/mindreader, the Mirage Envelopes are perfect for gaining secret information in such an innocent seeming way. Seeing as you get 5 (FIVE) of these amazing envelopes, I have put 3 in my show, use 1 for walk-around/EDC, and have 1 stored away in case I need a replacement. Even so, I'd happily buy 5 more. Thanks Richard!
