# Quality Park™ Double Window Redi-Seal Security-Tinted Envelope, #9, Commercial Flap, Redi-Seal Adhesive Closure, 3.88 x 8.88, White, 500/BX

Double window design eliminates the need to print or label your envelopes. Redi-Seal® closure can be sealed and ready for delivery in a matter of seconds -- just fold down the flap for a lasting hold. Blue security tint lining and wove finish.

-   Double window envelopes display sender and receiver addresses for invoices and billing statements.
-   The uniquely designed Redi-Seal® self sealing closure requires no moisture; envelopes have double flaps that press together for an instant seal.
-   Protect sensitive client information with a reflex blue pattern that obscures the details of the contents, even when envelopes are held up to light.
