MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

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

Not that good.

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

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

Not that good.

Liked the quantity.

I ended up using this as a stage 3, seeing I ruined 3 stage 4 tumbles,

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

its grit all 60/90 grit is the same
