The tray liners are 7" by 14" and perfect for lining jewelry trays to keep inventory free from tarnish while packed and shipped for up to 12 months or more.
The liners are made from a 12 mil. thick copper polymer matrix that bonds to and neutralizes tarnish causing gasses.
Color changes from copper to grey or black to indicate replacement with a fresh one.
While these are the ideal size for industry standard trays, they can be cut or trimmed to fit different size trays. They can also be cut to fit and line jewelry boxes or storage containers, bringing industry grade tarnish protection to the home.
