Black Clasp Envelopes

Secure document storage becomes easier with JAM Paper black clasp envelopes in 6 x 9, 9 x 12, and 10 x 13 inch sizes. Open-end construction loads papers through the shorter side, while reusable metal clasps allow repeated access. The solid black exterior creates a bold professional appearance. These envelopes hold reports, photographs, forms, certificates, and client packets for offices, schools, events, and creative teams.

Three document sizes cover compact, mid-size, and full-page contents without repeating measurements. Smaller styles fit booklets and half sheets, while the middle option accommodates many letter-size documents without folding. The largest size adds clearance for thicker packets. Metal clasps allow convenient reopening. Open-end construction handles office routing, presentations, record storage, mailing, and project files.

Projects needing frequent access benefit from clasp closures that open and secure more than once. Smooth midnight black paper distinguishes files, packets, and campaign materials from standard kraft or white envelopes. Short-side openings keep broad contents aligned during loading, while the size range covers compact and full-size papers. The reusable clasp style handles portfolios, contracts, photographs, reports, events, and distribution.
