Review on 10-Pack Ultimate Copper Scrubber, Pure Copper Scouring Pad by Chore Boy by Kianoush Hinrichsen

Exactly as described at a good price. Check it with a magnet to make sure you're getting copper. The problem with ordering a Chore Boy is that you can get a fake that is not real brass. Since I use this to clean the bore and cylinders of a revolver after firing lead bullets (wrap around the bore brush and use a low-speed electric drill), I need a metal that's softer than the steel I'm cleaning to avoid this to do to damage the barrel. That's the real deal.
