NATIONAL GEOGRAPHIC Hobby Rock Tumbler Kit
Works really well and my daughter is having great fun choosing stones from the beach and garden to polish. I was very happy with my purchase of a 'Hobby Rock Tumbler' first stage results were impressive I now look forward to the next and final stages. The kit was complete with a selection of semi precious stones, 4x grit grades and easy to follow instructions.
The NATIONAL GEOGRAPHIC Hobby Rock Tumbler Kit gets kids to enhance their rock collection or to start a new one. This fantastic science gift for kids includes a tumbler, sifter, learning guide, four polishing grits, plus nine types of real rough gemstones. This tumbler makes even the most irregular rocks look like dazzling gemstones with a simple, one-touch setting.
