These are specially manufactured cards that are ideal for card manipulation routines such as card production and are best suited for stage performances. The cards are printed on a special type of paper that is very flexible to facilitate back-palming production of the cards. The backs of the cards are flesh colored to make the cards easier to conceal. The cards are thinner than regular cards so that you can hold twice as many as standard playing cards. The faces of the cards are slightly different from regular cards and not recommended for use in regular close-up card magic. If you are a manipulator this deck of Manipulation Cards will be very helpful to you.
