Refill Grit Kit w MJR Tumblers Premium Quality Extreme Polish 12,000 Grit Sub Micron Aluminum Oxide Polish for Unparalleled Result. For 30lb Rock Tumblers w Silicon Carbide, Disabled and Veteran Owned

Top Notch. Switched from another brand and really love how it's making the rocks shine!!!

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

feels good to support a veteran

Super happy with my purchase but I will say I thought there would be alot more, I can tell the polish spilled all in the bag but that’s okay I don’t need anything other than the 60/90 grit but in the future I will all the bags were about a quarter full, used 2 in a half tablespoons of the 60/90 and most of the bag is gone now

The size was standard size happy with purchase

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.

I been tumbling rocks for 8 years now .This is the best that i have found .But they are misleading the customer they show full bags of grit and polisher But you get very little in the bag maybe enough to tumble 2 of 3 pound barrels . I know the price is very high for what we get .I can not afford it any more 2 times i ordered & both times to little of product .

good product, just what i needed

I purchased a rock tumbler, the first time I uses it I used the grit it came with. I wasn't happy with results. So looked into different grit. I only used the shine grit ( last stage) on the rocks that had already been tumbled with a shine grit and I was surprised at the difference. I haven't used the others but I'm sure the quality is just as good.

fast delivery from the US to the UK arrived with NO leakage of grit. Was confused about the amount as said 50lbs was thinking that was the wieght of it, but after checking more I realised was for a 50lb tumbler size . So was spot on wieghing 9lb. 60z.

I'm new to rock tumbling, I've used a few different polishing grits and this is the best one so far. I ran this polish cycle for 7 days and am happy with the results.

As described, arrived early, Thank you.
