Tons of abrasive for the price, and it works great as a suspension. No clumping or galling from it not dispersing in use. Particle size does appear to be correct for the 14000 grit I purchased. Review: This will get you to shiny! - I got a Lortone dual tumbler for Christmas and a kit of grit to go with it. I wasn’t getting the shine I wanted with the level 4 grit that came with the kit so I looked at reviews for a final stage grit and this one came up. I am not disappointed! This did the trick! I don’t want super shiny, just a shine but this grit can do both, all about the timing. Excellent product, totally recommend! ## Features - ULTRA-FINE 12,000 GRIT FOR FINAL POLISHING STAGE: This sub-micron 12,000 grit aluminum oxide is designed for the final stage of rock tumbling, helping refine stone surfaces after pre-polish.
