2 LBS 5/16" x 5/8" Ceramic Media for Rock Tumbling – Ceramic Tumbling Media for Rock Polisher, Use with Rock Tumbler Grit, Protects Rocks, Reusable, Rock Tumbling Supplies(8mm x 16mm)

Excellent for rock tumbler. I like that it’s environmentally friendly as compared to the plastic beads that are out there that contribute to micro-plastic pollution danger. They last a long time and do a good job.

This is perfect for my rock tumbling hobby. It keeps the rocks from cracking and marring the finish, while in the polishing stage

Great for running in larger tumblers. I run about 3 lbs of this in a 15lb barrel. They hold up great.

These pellets are great and stand up to the constant abuse of being bashed by rocks. They last from stage 1 thru 4. I have purchased these many times to help protect my rocks during the tumbling process

as described

Holds up well through many polishing cycles.

Nice ceramic media to use in your rock tumbler

Helps soften tumbling
