Give your gems the protection that they deserve in this zip-lock Anti Tarnish Bag. Made of bonded copper particles that is specially designed to neutralize all corrosive gasses that try to pass through and prevent tarnish. Effective for silver, gold, brass, copper, bronze and ferrous metals (iron based). The bag is non-toxic, environmentally friendly and fully recyclable—containing no charcoals, oils or volatile chemicals. The copper color of the bag is a saturation indicator; when it darkens to black, it's time to replace the bag with a new one.
