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

Love this 1200 grit !! And the company is awesome to deal with!!

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!

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

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.

Not that good.
