## Description

Product Description

Review: received - After 11 days, I received the grit! Polishes rocks nicely!
Review: Very little product. - 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.

### ⭐ Miniscule amount of grit.
*by J***F on 16 February 2026*

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.
