Tarnish is the corrosion caused by moisture and air, and the unavoidable enemy of your cutlery and tea sets, platters, collectible spoons, and jewellery. Soft cotton-flannel Silversmith Mitts are impregnated with polish and tarnish inhibitors so you can quickly and easily protect surfaces. Whip them on at the first sign of tarnish, and a quick rub keeps items sparkling new. No messy bottles, residue or fingerprints! Each pair lasts for over 100 uses, and also work on brass, copper and gold. Made in the USA.
