MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

The size bag is perfect .it preforms great. It usually arrives before its eta. Its a good value for the size package.i use a large rock polisher and it does many loads of rocks

Wasted a week trying to polish with this stuff. It did nothing.

. Breaks down too soon. no trace after 36 hrs of tumbling.

love ,love,love to see a plane rock turn into a shiny gem

Great product I would definitely buy again

Not that good.

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.
