3.5 Pounds Polishing Grits + Poly Plastic Pellets. Compatible with Any Brand Tumbler, 5-Steps for Tumbling Stones.
Just measure in the grit, add enough water to cover the stones, seal the barrel, and tumble. The only variable is how much product to use in your rock tumbler. We suggest 2 tbsp of grit per pound of stones, which is a good rule of thumb.
