These plastic pellets can be used in rock tumbling to take up extra space when there is not enough rock to fill the barrel or to cushion the rocks if they are soft or fragile. Plastic pellets can be reused many times with the same size grit. They are only used in rotary tumblers and don't behave well in vibratory tumblers. They are about 3/16" (4 mm) in diameter and float for easy separation from the rock.
