2.5 lb Stainless Steel Tumbling Media Pins, 0.039 Inch Diameter, 0.255 Inch Length

This stuff works great to tuble brass casings.

I used it to clean and polish coins and it worked great, I just added soap and water in a rotary tumbler and left it for a few hours and it came out perfect. Only thing is I highly recommend buying a magnet with a “switch” to “turn” it off to move and collect/separate the material because they really liked sticking to the wet coins because of how small they are.

I used this media to clean brass cases tumbling in a Harbor Freight tumbler. Works great!

Very sharp edges. Not able to use on soft metals until I can fix that.

This product worked better than I expected.

These are tiny and a bit fussy to work with, but they do a great job of cleaning brass in a rotary tumbler.

I use these for tumbling brass. These are awesome as you can just clean them instead of throwing out corn cob media. They are an expensive initial investment, but if you reload often like I do worth it. These things are very very loud though. The reason I give three stars is I would buy an ultrasonic cleaner if I could do it over with the money. If you dont want to deal with the ultrasonic cleaner, this is definitely a lot easier to use as you just clean the tumbling media and the tumbler and thats it. Not need to worry about vibration rates or dilution ratio of your cleaner. Just throw it in and turn it on. So I think it is great for cleaning brass as it doesnt need to be perfect. If you want perfect, get an ultrasonic cleaner.

Arrived on time, product came in a plastic bottle inside a box, much better than the pictured item inside a plastic bag

Excellent for tumbling, very fast shipping and does a great job on cases. I use about 2 lbs per 30 Magnum size rifle cases and am very pleased with the results

The stainless steel medium works fantastic. Cleans the primer pockets and the inside and outside of the shells. Add a little lemon fresh and they look new.
