Tonmp 5 Pound Rock Tumbling Ceramic Filler Media - 3/16 X 3/8 inch Small Cylinder Ceramic Pellets for All Type Tumblers (5 LB)

• Premium Non-Abrasive Ceramic Pellets – High-quality 5mm x 10mm cylindrical alumina ceramic media, non-toxic, static-free, and residue-free. Dries quickly and lasts forever—won’t spoil like plastic media!
• Protects & Enhances Tumbling Results – Acts as a cushion to prevent stone breakage, reduces tumbler noise, and improves grit distribution for smoother, more consistent polishing.
• Effortless Multi-Stage Use – No need to separate between stages—simply rinse and reuse the same pellets from coarse grind to final polish. Saves time and simplifies the tumbling process!
• Ideal Filler for Any Batch Size – Perfect for small or large loads, ensuring even tumbling action and preventing voids that can lead to uneven polishing or damage.
• Universal Compatibility – Works safely with all rotary tumblers and is perfect for polishing rocks, gems, glass, and more. A must-have for hobbyists and professionals alike!

As recommended, the same pellets should be used throughout the tumbling process, all stages. That way, the pellet surface gets the same abrasion that the rocks do. If you used new pellets in later stages, they would be more abrasive and could actually work against the tumbling media you are using.
