Refill Grit Kit w MJR Tumblers Premium Quality Extreme Polish 12,000 Grit Sub Micron Aluminum Oxide Polish for Unparalleled Results. For 3lb Rock Tumblers w Silicon Carbide, Disabled and Veteran Owned

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.

This grit and polish set is exceptional. 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.

This grit works just like all others, if used correctly. It is so easy to open and pour it into tumbler--the perfect amount for a 10-lb tumbler. Highly recommended.

I bought this set when I first started tumbling rocks. The grit works well. My only complaint is that I got 2 bags of the step 1 grit, 1 bag of step 3 grit, and 1 bag of step 4. I didn't get any step 2 grit.

Thanks for making such an awesome product it’s amazing

Kinda expensive for the amount of grit

Only used the 60/90 so far but I got very little grit in each package. This grit does not feel as strong/sharp as what came with my tumbler, coincidentally that is about how much you get in this order, enough for about one tumble like you get with your kit.

Absolutely wonderful product but where there is a positive there's also a negative. The way the bags are presentoo.Seem like you are getting a lot of product. Once hung in that bag , it comes to less than a half an inch of product on the bottom. Quit the deception quit wasting plastic and if you're gonna cell that smell of quantity. Please do not deceive the customers with the large bag.Cut it down your size
