Blue Marble National Geographic Rock Tumbler Media – The Ultimate Rock Polishing Supplies Kit, 4 Stage Bulk Grit, 1.5 Pounds of Ceramic Pellets, GemFoam Polishing Tumbling Media

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

Great tumbler. Use it frequently with no problems.

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

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

Word like it’s supposed to. Will buy them again.

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