The Universal #90 Kraft Clasp Envelope (UNV35264) is a durable, multipurpose mailing envelope designed for sending catalogs, brochures, photos, reports, and other documents that require flat, protected transport. Measuring 9 x 12 inches, this is the standard catalog-size envelope suited for letter-sized documents and standard presentation materials. Each box contains 100 envelopes.

Constructed from heavyweight 28 lb bond brown kraft paper, these envelopes are built to resist rips and tears during handling and transit. The open-end, square-flap design features a dual-closure system: a metal two-prong clasp with reinforced gummed eyelet for repeated reuse, and a moisture-activated gummed flap for a permanent, secure seal. The center-seam construction adds structural integrity, helping envelopes maintain their shape when fully loaded.

These envelopes are ideal for office, shipping, legal, and organizational use. They are compatible with standard postal and courier services and can be shipped via UPS or air carrier without hazmat restrictions. Backed by a manufacturer's limited one-year warranty.
