MJR Tumblers Refill Grit Kit for 3 LB Rock Tumblers Silicon Carbide Aluminum Oxide Media Polish

Buyer Beware! Read the small print on the size. This is a shockingly small amount of grit for the price. You might get 2 tumbles......maybe. I've paid less than this for 4 times the amount and just as good. Very misleading and sneaky.

what a rip. the other reviews don't lie, this is an even smaller amount of grit than you're imagining. it's like a sample kit. photos of my scale are attached (and measurements include the plastic bag.) i've only used level 1 but it was less than 3 tablespoons. for a 3-lb tumbler it's half of what i needed for a single batch. there's a reason a lot of sellers don't put the weights on the packaging.

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.

Thanks for making such an awesome product it’s amazing
