Less yuck: we promise you won't miss licking envelopes or crumbly, drippy sponges; complete your mailings, no accessories required. Store more, longer: reid-strip envelopes have a longer shelf-life thanks to the peel able strip that protects your adhesive from dust. Enhanced security: offer the protection clients deserve; a security tint makes envelopes hard to see through; a security pattern scrambles the appearance of text.
