Product Overview

I recently had the opportunity to try out the National Geographic Hobby Rock Tumbler Kit, and I must say that my experience with this product was nothing short of exceptional. This tumbler is specifically designed for hobby rock tumbling, which is a hugely popular hobby for both kids and adults. It features a durable motor that allows for time and speed control settings, as well as an improved, leak proof barrel with a stainless steel lid.

In addition to the tumbler itself, this kit also comes with 1/2 pound of rough rocks in nine different gemstone types, five jewelry fastenings, tumbler grit, a strainer, and our innovative GemFoam polishing foam. The GemFoam is what truly sets this product apart from other rock tumbling kits on the market its reusable and adds an incredible shine to your finished gemstones.

One thing that really impressed me was how easy it was to use this product. The instructions included in the kit were straightforward and easy to follow. I was able to set up the tumbler with minimal effort and begin using it right away. And despite being quite powerful, the motor is surprisingly quiet you wont have to worry about it bothering you or your neighbors while its running.

The Hobby Rock Tumbler Kit from National Geographic would make an excellent gift for anyone interested in rock tumbling. Not only does it provide hours of fun for children and adults alike, but it also encourages them to develop their skills in geology and science. I highly recommend this product for anyone looking to learn more about rocks and gems!
