Business Source BSN03141 No. 10 Double Window Envelope 500

Product Description

The BUSINESS SOURCE BSN03141 is a No. 10 double window invoice envelope built for high-volume billing and statement mailing. It features two poly windows that expose both the return address and the mailing address printed directly on the inserted document, eliminating the need for separate address labels. The envelope is made from 24 lb paper with an inside privacy tint that blocks the contents from view in transit. The self-sealing closure uses a double-flap design: a protective lower flap shields the adhesive strip before use, then peels away so the envelope seals with firm hand pressure and no moisture required.

This envelope is designed for standard 8.5 x 11 inch computer-generated invoices, statements, and remittance documents. It fits the typical folded tri-fold insert used in accounts payable and billing workflows across office, accounting, and administrative environments. Sold in a box of 500, it suits recurring billing runs where consistent throughput and secure presentation matter. The privacy tint makes it appropriate for any mailing where document contents should not be visible through the envelope stock.
