MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

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.

Received as advertised, and timely.

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

Not that good.

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.

Great product I would definitely buy again

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