Worked as advertised
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.

Miniscule amount of grit.
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.

Great product deceptive practices
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
