MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

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

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

Love this 1200 grit !! And the company is awesome to deal with!!

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

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

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

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.

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