I recently purchased the NATIONAL GEOGRAPHIC Rock Tumbler Refill Kit from Amazon, and I must say that I am thoroughly impressed with the quality and variety it offers. The kit includes 5 pounds of unpolished rocks and gemstones, which provides an enormous variety for tumbling. The rocks are of excellent quality and come in different shapes, sizes, and colors, making the tumbling process exciting and educational. The rock tumbler grit and polish refill that comes with the kit is exceptional. It effectively smooths and polishes the rocks, giving them a beautiful shine. The included instructions are clear and easy to follow, making the tumbling process a breeze, even for beginners. What I appreciate most about this kit is the value for money. The amount of rocks and gemstones provided is generous, ensuring that I have a continuous supply for multiple tumbling sessions. The quality of the rocks and the effectiveness of the grit and polish make this kit worth every penny. Overall, the NATIONAL GEOGRAPHIC Rock Tumbler Refill Kit has exceeded my expectations. It offers a wide range of rocks and gemstones, excellent grit and polish, and is a great investment for anyone interested in the art of rock tumbling. I highly recommend this kit to both beginners and experienced tumblers alike.

Nice assortment of stones. Easy to use directions and supplies.

Purchased for my daughter (14)and niece(6). They absolutely loved them. Great value, easy-to-use and ready to go for tumbling. Fun for kids and adults. We have a harbor fright double barrel tumbler and we have both barrels going at the moment. I've herd the grit isn't the best, but we gonna give it a try. I will do an update on the grit in a month-ish when we make it through all 4 stages.

There was a lot of rocks. All different sizes. That I did like but there were a lot of rocks, at least a pound worth, that were unusable. They were way too small to last through the tumbling process. So that's a waste I wasn't very happy about that. But it does come with extra steps one through four grit and I was pleased with that because I didn't read that in the description so that was a nice surprise. Each pack comes with about a tablespoon worth of grit so you'll have to use multiple packs if you are using a tumbler that takes more than a pound. Overall would purchase again because it is a good deal for the money just wish there was more usable rocks.

My favorite tumbler

Lots of rocksGood sizes some small but most are acceptable

I like that they sent what was advertised

If you have a tumbler it's nice to get kits with the polishing powder included. Kids like it. Cheap things for necklaces etc but that's expected.
