Archivists and conservators both worry about metal corrosion. Anti-Tarnish Strips prevent silver, gold, copper, brass, nickel, bronze and pewter items from tarnishing during shipment, storage, and display. These anti-tarnish strips won't off-gass or leave a residue, and work with all packaging including jewelry and display cases, poly bags, and cardboard containers. They prevent tarnish from forming by absorbing or 'trapping' atmospheric pollutants such as hydrogen sulfide and sulfur dioxide. In a tightly sealed container,

anti-tarnish strips will protect for at least six months.
