Thumler's Tumbler - Tru Square Plastic Tumbling Beads - THU320

Plastic tumbling beads, also known as plastic pellets or filler media, serve an essential role in rock tumbling. They are specifically designed to:

• Cushion and protect rocks during the grinding and polishing process.
• Reduce noise and minimize damage to stones.
• Ensure even tumbling by filling empty spaces in the tumbler.

These beads are typically used in the later stages of tumbling, such as pre-polish and polish, to provide additional cushioning and prevent the stones from chipping.
