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

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.

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.

Worked great.

The size is just right for my rock tumbler

Im happy with it in my vibratory rock tumbler.

Exactly as advertised. They work fantasticslly

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.

Works great in my 15 lbs. rotary rock tumbler.

Good quality filler and works well.

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.
