Tarnish and Corrosion Protection for: Jewelry Watches, Silver Gold Tableware Silverware, Brassware, Copperware and Coins. Zerust anti-tarnish drawer liners combine the power of Zerust anti-tarnish technology with a heavy duty anti-slip PVC drawer liner. When used in an enclosed area, the Zerust molecules create a layer of tarnish protection around your silver. Zerust is non-toxic, FDA approved food-safe and leaves no residue or odor. It is a molecular vapor that inhibits tarnishing but will vaporize off the surface of your silver when taken out of the enclosed area where it is being stored. Protect your special occasion silver or use it as a liner in your jewelry case for up to 5 years. Drawer Liner Size: 12" x 72"
