NATIONAL GEOGRAPHIC Hobby Rock Tumbler Kit - Includes Rough Gems

NATIONAL GEOGRAPHIC Hobby Rock Tumbler Kit - Includes Rough Gems:we obsessively test and report on thousands of items each year to recommend the best of everything. Fun project.I wasn't sure about the size when I first ordered. It is smaller then I thought but large enough to hold a small batch of rocks. I am new at rock tumbling and didn't realize it takes about a month of steady running and weekly changing the grit to get the end result. I am enjoying the process and the tumbler is very easy to run and very sturdy. I am happy with my purchase.san antonio mall,new product!!,long beach mallNATIONAL GEOGRAPHIC Hobby Rock Tumbler Kit - Includes Rough Gems
