A classic trick made better than ever.
The magician shows a pocket knife with a white handle. Passing the knife through his hand, however, changes the color of the handle to black. The knife is shown on both sides to be either white or black, whichever the magician chooses. At the conclusion of the color changes, the knife vanishes and reappears in the magician's pocket, at which point it can be handed out for examination.
The knives are real pocket knives and are suitable for everyday use. Made in China and packaged by FUN Inc.
