Quality Park #ad - Save time with self-stick: quality Park 10 Security Envelopes have a strong peel and stick closure that helps you fly through mailings in record time.

An excellent value: bright white 24-lb paper makes an impression for business mailings and personal correspondence; get 100 4-1/8 x 9-1/2 inch envelopes. Store more, longer: redi-strip envelopes have a longer shelf-life thanks to the peelable 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. Less yuck: we promise you won't miss licking envelopes or crumbly, drippy sponges; complete your mailings, no accessories required.
