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.

Don't trust the kits on here, you need 8000 and above in final stage to get a good polish. This works really well. Always burnish afterwards to complete the stones. ## Frequently Bought Together - 2 Pounds of MJR Tumblers Premium Quality Extreme Polish 12,000 Grit Sub Micron Aluminum Oxide Rock Polishing Powder. for Unparalleled Quality and Performance.
