This special deck has 54 cards printed with six sets of different ESP symbols (nine each). Each symbol has a different color: circle (red), cross (black), triangle (green), square (brown), star (yellow), and wavy lines (blue). On the back, the cards have the same white border as regular playing cards. But the back of each card includes a secret mark to help you quickly identify what symbol is on the face of the card. The audience won't notice this secret mark at all. Using this deck of cards, you can perform predictions, fortune telling, or any other ESP trick you like. (Poker size- the finest Belgian-made cards/English instructions are included.)
