MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

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

This product was phenomenal. It helped me take a whole week off of the time needed for my tumbles! Highly recommended if time is a concern!

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

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

Not that good.

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
