This is the best polishing cloth for brass and copper we found.
Made in Japan. The cloth is 3 3/4" x 2 1/2" and will last a long time. Even when it gets black, keep using it until it stops giving you a good shine.
Do not use on our other models that have a lacquered copper handle, like the Vortex model. Only use it on raw metal that can tarnish. This cloth leaves an excellent protective coating on metal.
