2 LBS Rock Tumbling Ceramic Filler Medi Rock Tumbling Ceramic Filler Media Non- Abrasive Ceramic Pellets for All Type Tumblers 3/16 X 3/8

They work for tumbling my rocks

At first I was under impression that this could be used in place of grit. That didnt work out for me. When added to # 3 I had favorable outcome !

I am new to tumbling and this was my first purchase after my initial supplies that came with my tumbler ran out. Had no issues using this size and my rocks are looking great!

I ordered 4 pounds of media and only received half, extremely disappointing

Good product

My daughter got into rock collecting and a few months ago we finished our first month-long rock tumble of our own. The results were good... but I noticed a lot of the rocks had broken apart in the last few stages. The rock tumbler I bought suggested filler media like this, so for our second go I tried these out. SO MUCH BETTER! I dont think any of the rocks broke apart and these things still look brand new. They should start packing these with rock tumblers!

Works like a charm, wife polishes rocks in the garage every day with this product.

Took a bit longer than I expected for delivery but the product works great and is a staple in my tumbler

Will order again. Very satisfied.

They are very tiny but will help cushion softer stones, and carry the grit into the nooks and crannies. Will definitely buy more.
