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

I use it in a wet tumbler for cleaning firearm brass. I used to use a vibrator with walnut shells, but I thought it didn't clean well. These in a wet tumbler are the best for me. I put the pins in the bucket first, then a capful of Brasso, a little dish soap, then the brass and water. I change the water until it is mostly clear then the last run is a water only rinse.

Needed less then I thought I did. Great item works for cleaning brass in a wet tumbler

Cleans brass really well

Good for what they were made for. Helps get my brass very clean

I used it on about 500 .45 caliber casings one they did a spectacular job. Only rolled them in my tumbler for about an hour and they look like brand new casings from the factory. Easy enough to use just dump them in and let em roll. Being stainless steel they will never rust.

Need twice as much to work in a larger tumbler

The pins arrived in perfect condition. I plan to use them to do a final polish of white metal model parts. My test run worked great. I used about half of the pins in my tumbler with water and a few drops of dish detergent, and after about an hour the test parts were a goodly way to being polished, even without any prior file and sandpaper work. You may want to wash the pins prior to use, as the water I used had turned very black. The pins are strongly magnetic.

Exactly as described

all good

I bought these for cleaning brass cases. They're much more economical than getting them from somewhere like Frankford Arsenal, and they do every bit as good a job. FWIW - they're almost the exact size as FA pins. One issue with these (and others like FA pins) is that they become magnetized relatively easily, which can be a bit messy as they'll stick to the sink or anything metal. I suppose drying them in the oven at max temperature may work - I've tried at 220 F and that isn't hot enough.

As advertised. Pins are uniform and good quality.

Works amazing especially when you are tumbling cases that the primers are removed it cleans out the primer holes extremely well I just wish I could buy the smaller size in the large pound packs as well

Pins are the same as more expensive pins from Frankford Arsenal. Both made in China, just have different containers.
