You can tell it was crafted by people who genuinely care — not just about rocks, but about the process and purpose. This company emanates expertise and enthusiasm, and that shows in the results. My rocks came out more beautiful than ever and I would prefer to buy only from these rock guys. The picture is of some rocks from my apartment landscaping after the process . The instructions are detailed but easy to follow. It’s not your typical instruction manual, rather a sincere document created by the seller from the heart (their tips and tricks included!). It’s really unique and special. I’ve been using a “gimmicky” tumbler set for my HS STEM program and at home with my kids. As a teacher, is a great tool for many lessons and even many subjects. Review: This is TRUE GRIT! - This is simply some of the best quality tumbler grit I have used. If you do the first three stages properly, then the 12,000 girt polish will be perfect. All in all this is good, works well in each stage, easy to use. the only thing that might make it better would be to package it in bottles instead of bags, but honestly, that's about it. ## Features - COMPLETE 4-STAGE ROCK POLISHING SYSTEM: This refill grit kit includes all four essential stages of rock tumbling—coarse (60/90), fine (120/220), pre-polish (400/600), and ultra-fine 12,000 grit aluminum oxide polish.
