Works great for Stone washing knives. I use these along with 5/8,7/8 and the mixed size filler. You need to run this media for a few hours with 60/90 silicon carbide before tumbling to smooth all edges prior to stone washing a knife blade. works great for me.

Tumbled some brass that I'd annealed and a lacquer coating that was on them burnt off and stained all the casings. These cleaned that right off in 20 minutes. My other aggressive tumbling media couldn't do that after running for 4 hours.

Works well, they do wear down faster than expected but they do a good job and work fast. Deburred and have an even finish to some parts from my CNC machine in about half an hour.

This product will remove burs and rough spots. Not for polishing.

I've used several types of media and I like this the best. The size of the stones are perfect for small parts and worked well with stainless steel parts.

Almost double of the cost of some sellers out there and wears out really fast like in 40 hours of tumbling.

Work great in my large tumbler for heavier items. Highly suggest this size and shape.

Very useful for tumbling. Taste has a long way to go, somewhat disappointed in the overall flavor. Recommend adding some spices if you are going to chew on these.
