MJR Tumblers Refill Grit Kit w Premium Quality Extreme Polish 12,000 Grit Sub Micron Aluminum Oxide Polish for Unparalleled Result. for 6lb Rock Tumblers w Silicon Carbide, Disabled and Veteran Owned

Great stuff for rock tumbling

Works as advertised.

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.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.

Love the amount in this order! Perfect size grit for each stage! Fast shipping!

Quality aside...the amount of product sent is not what I thought I was getting. My fault for not reading the description better. This makes the product extremely overpriced and I will purchase a different brand next time.

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.

Arrived quicky and works just fine. It arrives with a coupon each timeI purchase this item, but I am unable to use it on this site, but I will continue to purchase this grit in the future.

Just received my package... but its just 4lbs. Read carefully,. Don't be tricked, it has nothing to do with "18lbs tumblers". Yes, i was expecting 18lbs of grit, fealing deceived with only 4.

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.
