Frankford Arsenal 909191 Stainless Steel Tumbling Media, 5lb

The Magnetic Stainless Steel Tumbling Pins are designed to clean brass cases giving a "like new" look. Unlike other media like corn cob or walnut, stainless steel doesn't create dust and also cleans the inside of cases, primer pockets, and flash holes. Stainless steel also doesn't damage brass and lasts for multiple uses.
