National Geographic Professional Rock Tumbler and Supplies

National Geographic STEM professional rock tumbler with additional gemfoam supplies. Includes motor unit with digital controls for days and speed. Electric powered toy. Rock tumbler was used twice, worked great but my son never really got into it. The powders in the tumbler was used, but the supplies box has never been opened. With both boxes you are ready to start making your own gems! Retail for both is $200. Selling for $60. If the ad is up, the set is available.
