Our 7" x 14" Corrosion Intercept® Anti Tarnish Poly Tray Covers prevent tarnish of your jewelry for up to 12 months or more. The cover works by absorbing and neutralizing tarnish-causing gasses without leaving any deposits on items it protects. The cover has a built in saturation indicator - when the cover begins to change to a gray or black color, it's time to replace it with a new one. Trim the cover as needed to fit half-size trays. Corrosion Intercept is non-toxic, non-abrasive, recyclable and environmentally friendly,
