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

Wow what a time saver. This will clean your brass cases in under an hour or if you give it 1.5 hours it will also clean the primer pockets as well as inside the case. There is nothing that compares and I wish I had have bought one a long time ago!! High, highly recommend getting one. No more cleaning the primer pocket, its now a thing of the past. As for longevity I havent had it that long. But given the design of it, I would expect it to last quite a while. Also like the hexagonal shape over a round tumbler. Seems to agitate the media and brass better. Also, the see through perspex container means I can see how bright they are without having to take the lid off. All in all, I highly recommend it.

Perfect for tumbling brass. Makes a ferocious mess if you drop it on the floor. Cleans up easy with a strong magnet. I take a strong donut magnet and put it in a ziplock bag. Then drag the bag over the medium or through the brass to pick up the media. Put the whole thing in a bucket and then remove the magnet from the bag. All the media falls into the bucket. So much easier than trying to shell stuck media off the surface of the magnet!

Great for cleaning brass!

Tumbling Pins worked great. They are a little smaller than I thought , but thats my fault, they still work though
