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 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 absolutely love this rock polishing grit. I have had very good luck with it.

Having used this grit assortment many times before I know I can depend on this product to work well with my rock polishing. For fellow polishers with a 15 pound tumbler, this a good kit to buy. It prevents you from having to purchase multicable smaller kits.

Kind of annoyed that they don't have the nice labels as shown in the photos, would have made it easy to keep separated. Instead there's these small clear labels on the bags that you have to find....That's basically half star off instead of a full star....Fortunately, identifying the grits by sight looks like it should be fairly easy, especially the 12,000 grit AO polish powder - wish that was available on its own.... but I did find a diamond powder / polish mix alternative that might work at a similar cost per pound.Would have been real nice if the description was a little more clear in what you get.... i.e. 3lb media for 15lbs of rocks... which is the other half star off.... I was looking at a 7.2lb of media kit for about the same price only it had the 1500grit AO polishing powder.

Great product and have used it several times.

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 .

Great stuff for rock tumbling

Great product.I noticed some complaints about the amount in the bags they ordered.If you ordered for a 3 pound tumbler, that’s what you get. Enough grit in each bag for one run of a 3 pound tumbler.Not sure what they expected….?Anyway, I get great results with this grit.I do do one more step with Tin Oxide but it’s really not necessary.Final step of borax for a day to get the rocks good and clean.Very happy with this product.
