## Description

Polly Plastics Rock Tumbler Grit Refill, Final Polish 1200 Fine Aluminum Oxide, Stage 4 for Tumbling Stones (2 Pack) (1 lb.): desertcart.com: Industrial & Scientific

Review: Good grit - This grit worked great for my first ever Columbia river rock polishing experiment. I didn't have enough stage 1 grit from the "starter" pack I originally purchased. I added another 3 TBSP to my tumbler and the rocks look great at stage 1
Review: Best rock tumbling grits on desertcart - I have been rock tumbling for over two years now and I have purchased this brand multiple times and will continue to be a return customer. The grits work exactly as expected for each stage of tumbling. Important notes: - Get the one that has the ceramic filler - not the plastics. The ceramic will last way longer and be better on your rocks. - Also - watch some YouTube videos on how to tumble rocks and switch between stages. There's some important tips to make sure you get the best results. Michigan Rocks YouTube channel has some great instructions on it. For the price and quality, couldn't be happier.

## Questions & Answers

**Q: Can I use this with my handheld rotary tool as a polishing compound?**
