This is a Sears Tumble Stones rock polishing kit from the 1970s. I used this once and it worked great, my family couldnt put up with the grinding noise at night. A great way to get introduced to rock polishing. Comes with 3 full cans of polish, pre-polish, and fine grits. The coarse and medium grits can be found online or at rock shops. Comes with original instructions. Made in U.S.A.
