I am surprised at how well this kit works. Just follow the instructions and you’ll have wonderfully polished rocks. I bought this kit and a separate tumbler just out of curiosity. I have so many rocks on the shelf now I’m sure my wife is hiding them. Definitely worth the purchase.

This kit contains all that is required to produce polished stones of a high standard. The gemfoam gives a quality polish to be proud of. Those who tumble more often may require a bulk buy but this kit would suit most hobbyist.
