National Geographic Rock Tumbler Refill Kit – Rock Tumbling Supplies Including Rock Tumbler Grit and Polish Refill, Ceramic Media, GemFoam, 3 lbs Madagascar Rocks for Tumbling, Jewelry Accessories

Great tumbler. Use it frequently with no problems.

My first experience with a rock tumbler and I love it. Works just as explained in the directions.

These are the same grits that come with the tumbler kit. The scoop that comes with it is a nice addition. I've found that some grits get used faster than others, so it may be worthwhile to find a supplier that sells individual grits. Depending on where you find your rocks, you may find that some of the heavier grits are not needed as much as the finer grits. Most rocks I've polished came from riverbeds and are fairly smooth to start with. In my experience, you can start with the 3rd grit on these and still get the desired results in less time since you can skip the first grit or two which is about 2 weeks of tumbling. Another tip, get some dishes like cake pans or casserole dishes at the dollar store and pour the water/grit from the tumbler into them and let the water evaporate. I have one pan for each grit. You can then reuse the media several times before discarding it.

A week of tumbling my stones in the "polish" yielded dull, no-shine stones. Save your money, buy something else. By the time you finish the 4th stage, the return window will be closed!
