Chips by Anthony Blake, David Harber These chips have been made by the same company that makes gambling chips for major casinos. Each chip is made from a long-lasting composite material designed to last a lifetime and they weigh a casino-standard 10 grams each. The colors/inks used in the chips are embedded within the composite so they cannot rub off with use. Each E.S.P. CHIPS package comes with a set of 10 chips (2 sets of the standard Rhine/Zener symbols), a drawstring carrying bag, and complete instructions and routines by such noted mentalists/magicians as Max Maven, Rick Maue, Jack Kent Tillar, Banachek, Greg Arce, Jheff and Anthony Blake. Each chip is individually marked on the back so that you can tell what the symbol on the opposite side is. The markings are easy to read for those who know but completely baffling and hard to find for spectators and lay audiences. RARE AND HARD TO FIND NO LONGER MADE!
