Rock Tumbling kit
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.

Great little starter kit
Functions as described. This is fun for kids and adults. The tumbling process can be kind of noise but worth it. This helps speed the process of tumbling. The small size makes it easy to store. Great gift idea for any rock hound G

Good tumbling media!
Love this media, works well. I haven’t made it to the polish stage yet so I’ll update my review once I do!
