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

Very helpful in polishing, filling space in the tumbler and making the process more quiet.

This media was great! I used it to rubble a knife to get an acid stone wash and it came out great, especially for my first time!

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.

good quality

Perfect for project

Good quality filler and works well.

Great purchase

Great product! Very satisfied

Didnt do much in my tumbler.

So the price is great! The thickness of the pellets is amazing because they can be rinsed off and reused! So happy with this product.
