Why Mylar? Mylar is widely accepted as the best way to store and preserve paper-based collectibles. In fact, the U.S. Library of Congress uses only Mylar and other approved Polyester films to preserve their paper documents.
Mylar will never yellow or put harmful materials into the item it is protecting. As an added benefit, Mylar has a superior brilliance and clarity that truly showcases your collection!
Here are the details on our #10 Envelope Mylar Sleeve:

*Mylar D® is a Polyester film manufactured by DuPont Corporation. The production of Mylar has actually been discontinued, although the term Mylar is still widely used as the name for any Polyester film. For this reason, we use the term "Mylar" to indicate any Polyester film (Mylar, Melinex, etc.) that is approved by the Library of Congress.
