3LB Rock Tumbler Grit and Polish Refill Set, 4-Step Professional Polish Rock Tumbler Grit to Unlock Stunning Polished Stones. Ideal for National Geographic, KomeStone, and Other Polishers and Tumblers

Fast shipping. It works the way it should

great!

Arrived quickly and produces a quality polish.

Have been using for a few polishing cycles, and so far have been impressed with the results. Biggest con is the measuring spoon doesn't fit the lid, which is a huge oversight. Rocks get nearly perfect after following the recommended length and time, we can't wait for more cycles!

Worked perfectly! Just what I needed for rocks I found in the yard. Not a professional.

Works as described. Shipping was fast. Kids love their rock tumbler so we use the grit and polish a lot. Would recommend and will buy this again.

This looks like a very nice and sturdy unit. They give you several belts for the future. There’s enough grit for one batch. There are four stages that take about one week apiece so it’s nearly a one month long project for a handful of rocks. One issue was where to put the thing. It makes a lot of noise. Plus it walks off the surface or walks around so if you put it on the countertop, eventually it’s going over the edge. I am in stage two and was very impressed with the results of stage one; they give you some pretty square gem cuttings if you want to do those. I chose to do common gravel that I find in my road. I do believe they’re going to be beautiful in the end.

This multi step rock tumbling set worked great!
