Tonmp 5 Pounds 5/16 X 5/8 Inch Rock Tumbling Ceramic Filler Media - Large Cylinder Ceramic Pellets for All Type Tumblers

Good quality filler and works well.

These were 100% as advertised. They rinse totally clean so they can stay with the rocks for all 4 stages. They do a great job of smoothing and polishing without damaging the rocks. Far superior to plastic beads due to ease of use and rumbling outcomes.

Worked great in my tumbler!

Fast shipping... great product...would buy again...

good quality

Excellent shape, size for my larger petrified wood that goes into either of my large tumblers. I use it in both my 18 lb vibrating tumbler and my 15 lb rotating tumbler. Great price for this product especially since you are able to wash and reuse again.

Great product! Very satisfied

Didnt do much in my tumbler.

I love poly plastics. That’s my brand. But I never get enough media in my kit plus the price is double. This is cheap. Huge so they last longer. The amount for the value is a steal. I will be reordering and all my fellow rock hounds need to add this to the tool box.

This did the trick. My rocks dwindled in size so too maker up room in the tumbler, these worked perfectly. The batch I used seems good enough for another run, too.
