As far as I am aware, these are the best ESP cards on the market. The design on them (all-seeing
eye) is the original reason I was interested in buying them. They look very mystical with that
design. I always hand these out to spectators for inspection and ever nobody finds any markings. The
quality is very, very good. I do not riffle shuffle these or do anything that bends the cards much
because they are so nice. The instruction booklet that comes with it has many colorful diagrams with
instructions from top names in mentalism. If you are not looking for anything fancy, then the Royal
brand of ESP cards might be better for you to save money.
