The pro grip multiplying balls have been specially formulated from a special silicon rubber to make gripping and manipulating the balls easier than ever. The multiplying balls effect is a classic of magic. The basic effect is as follows: One ball is shown between the finger and thumb. With a gentle shake of the hand a second ball appears between the fingers. This is moved to between other fingers, then another ball magically appears from nowhere. This is repeated so you have 4 balls held between each finger. They can now be placed down into a box or hat, or they can vanish one by one until all are gone. Includes basic instructions as well as a complete routine. Includes four balls and a shell.
