The basic effect: Four small silk hankies of four different colors are placed into your hand. With just a snap of your finger, all four silks combine to form a silk of the four colors. PLEASE NOTE: As the name says, these are small and meant to work with a thumb tip. If you are not familiar with this prop, you are in for a treat! Although it will require some effort on your part to make this work, it is well worth it. The thumb tip may or not be included, so please make sure you read the descriptions on each variant before making your purchase. Versions: Mr. Magic - The four separate silks are red, yellow, green and blue. Instructions included, but not the thumb tip. MAK Magic - The four separate silks are blue, red, white and green. Comes with basic instructions and an OK (but not great) thumb tip.
