The Marblescope Kit uses a marble to generate brilliant images. It is made from three pieces of .05 aluminized front surface mirror, which creates a much sharper and brighter image than ordinary mirror. The kit contains three precut pieces of front surface mirror, four marbles, a brass split ring marble holder, felt cushion pads, full-size patterns and complete instructions.
