Quality Park #10 Redi-Seal Security Envelopes offer a reliable solution for confidential business mailings. These standard #10 envelopes measure 4-1/8" x 9-1/2" and are crafted from durable 24 lb. white paper, making them well-suited for invoices, statements, correspondence, and general office mailing needs.

Each envelope features a Redi-Seal self-adhesive closure with a square flap that requires no moisture to seal — simply press to close for a secure hold. A unique double-flap design prevents envelopes from sticking together during storage. The interior security tint pattern obscures contents from view through the envelope, protecting sensitive information in transit. The long-side flap placement makes filling and inserting documents quick and efficient. Made in the USA. Box contains 500 envelopes.
