I bought this extra grit for my rock tumbler. It works great and leaves your rocks super smooth. I'll be buying more for my grandpa this Christmas for his rock tumbler.

Excellent kit for beginners. Works perfectly with the tumbler I have. Love using the foam for final polishes.

Everything is included except the rocks, tumbling compound an water. Good clear instruction. You may want to experiment with the length of tumbling with each grit you use based on the subject you are polishing. Good, clear instructions.

My daughter was so excited to refill her rock tumbler. This set works great.
