This is a giant pack of ESP symbol cards. Cards measure 11" tall by 7" wide. Consists of 25 cards, 5 cards each of five different designs. Designs include circle, cross, wavy lines, square, and star in five different colors. Great for working before larger audiences. Its size also implies that it is not a deck of playing cards, and no trickery normally associated with card tricks is involved. Comes with a 15 page booklet describing some of the better effects specially suited to large cards. Very good value!
