The classic color changing knives brought bang up to date. Chad long uses 2 USB FLASH DRIVES. One Red one BLACK. The flash drives magically change places at your fingertips. The routine is both visual and logical. The kicker comes when one of the drive stretches 3 times its length. It must be a larger drive, right.
Easy to do, perfect pocket trick. Comes complete with custom made red drive, black drive and super stretched drive. No Re-set.
