Display the receiver addresses through the window. 500 envelopes in each box: ideal for both everyday office use and bulk mailings, each box of Quality Park #10 Left Window Security Tinted Envelopes provides a long lasting supply for your Standard Business Mailings! The reflex blue pattern lining the envelope's interior makes it impossible to see the details of the contents, even when held up to the light.

Redi-seal self adhesive closure: with the redi-seal closure, envelopes do not require moisture to seal. Mail invoices, statements and other important documents with confidence. The unique double-flap design keeps the gum from sticking before use.

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. Save time with self-stick: quality park #10 Security Envelopes have a strong peel & stick closure that helps you fly through mailings in record time. Enhanced security: offer the protection clients deserve; a security tint makes envelopes hard to see through; a security pattern scrambles the appearance of text.
