MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

Great product I would definitely buy again

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!

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.

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