NATIONAL GEOGRAPHIC Rock Tumbling Media – GemFoam Reusable Rock Polisher Foam, Use After Rock Tumbling Grit Cycles, Adds Shine to Tumbled Rocks and Minerals, Rock Tumbling Supplies

My first experience with a rock tumbler and I love it. Works just as explained in the directions.

Im a kid again with this stuff! Easy to use, idiot proof instructions! Great outcomes.

excelente producto

We bought these looking for another way to try to get our rocks to shine with a wet look. They make our rocks a little more smooth, but we still can’t figure out how to get the wet look on them. They are reusable, but you need to make sure you keep track of what you used them with or after because you don’t want to add grit to them. I would say they worked okay. The price was decent.

This make rock tumbling so much easier. Each bottle it number. So you know what one to use.

Works great

I have only done one round in my tumbler, and one for a few days. But there was some shiny rocks already. They work great, I wish there were a few more cubes so I could do bigger patches but, theyre awesome

This is a great item. It arrived fast and is exactly what I needed. My glass is in the rock tumbler now and getting smoother by the hour! This will be by go to product when I need more!

It helps shaping stones too..it is a little sound and I'm living 2floor so I put a box on it to make the noise more silent

facile a utiliser apres avoir utiliser mon 1200 grit

exactly as pictured

die Größe ist ok, es reicht für einige Durchgänge in der Steinetrommel

Indispensable pour utiliser la polisseuse de mon fils. Il y a de quoi faire pour un moment.
