This is a loose buff made of 100% long strand Egyptian cotton, the Brilliant Buff is impregnated with the same patented chemical as our rougeless polishing cloth. This chemical agent is harmless to the environment but leaves a light residue on precious metals. This invisible residue inhibits tarnish. Excellent for that final buffing, then just wipe with a dry cloth and you'll see a beautiful luster. Size 4-1/2" x 1/2" thick.
