MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

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!

Not that good.

its grit all 60/90 grit is the same

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

its grit all 60/90 grit is the same

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

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