The BUSINESS SOURCE BSN36661 is a brown kraft clasp envelope designed for secure document storage and mailing. Measuring 6.5 x 9.5 inches and constructed from 28 lb kraft paper, these open-end envelopes feature metal clasps plated for rust resistance with reinforced attachment points and rounded edges to prevent tearing during handling. A large flap with deep gumming provides a firm seal once closed. Each box contains 100 envelopes, making this a practical supply for offices, mailrooms, and document management operations that require a reliable, reusable closure envelope.
These envelopes are suited for organizing and mailing standard documents, forms, contracts, and photos in office, legal, medical, and administrative environments. The 6.5 x 9.5-inch size accommodates letter-size and smaller documents folded once, or smaller flat items without folding. The clasp closure allows repeated opening and resealing, which is useful for internal routing and records management workflows.
Designed as a general-purpose clasp envelope for standard office, mailroom, and records management applications requiring a 6.5 x 9.5-inch open-end format.
No tools are required for use. To seal, insert documents, press the clasp prongs through the grommet hole, and fold prongs flat against the flap. Apply light pressure across the gummed flap for an additional seal. For secure mailing, verify that clasp prongs are fully flattened to prevent snagging in postal processing equipment.
