These Silver Drawer Inserts are manufactured with Pacific Silvercloth®, a specially designed material with invisible silver particles embedded into the cloth. These particles absorb tarnish-producing gases before they reach your stored silver. Pacific Silvercloth® is nationally recognized as the premier fabric for prevention of silver tarnish. Available in two standard sizes, each insert includes a cover flap to assure complete anti-tarnish protection. Please contact us for ordering info and prices.
