MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

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

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

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

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

Liked the quantity.

So frustrating!!! I was so excited to open the tumbler after the final polish, only to find dull rocks. I used this brand a few years ago and was disappointed. I ordered it again by mistake but figured I would give it another try. TERRIBLE! Such a waste of money!!! I am having to repeat the polish stage with a different brand and wait another week.
