MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

This product is not a polish. It doesnt shine anything and took the sheen off items that were already polished. Do not purchase this polish. It doesnt work.

So frustrating!!! I was so excited to open the tumbler after the final polish, only to find dull rocks. I used this brand a few years ago and was disappointed. I ordered it again by mistake but figured I would give it another try. TERRIBLE! Such a waste of money!!! I am having to repeat the polish stage with a different brand and wait another week.

Not that good.

it does the job pretty good, I use it in a tumbler to sand large pieces instead to have to sand by hand.

It is pricey. Worked ok but not that much better than the 90 grit which is much less expensive
