Product Identity

Business Source 36667 clasp envelopes are heavy-duty Kraft mailers sold in boxes of 100. They measure 12 by 15-1/2 inches and use 28 lb stock for durable document handling. The open-end design with metal clasps suits offices, schools and mailrooms that ship or store bulky paperwork.

Upgrade Context

These envelopes replace lighter-weight mailers or non-clasp styles when contents need a rust-resistant metal fastener and deep gumming on a large flap. The jump is worth it when documents are thick, frequently reopened or must stay sealed through rough handling.

Fit and Alternatives

They suit anyone mailing contracts, catalogues, blueprints or legal files that exceed standard letter size. Buyers who need peel-and-seal convenience, window fronts, padded cushioning or a smaller footprint should look at other envelope types.

Questions about this item

Will the 12 x 15-1/2 inch size fit in a standard letter tray?

The envelope measures 12 by 15-1/2 inches, which is larger than standard letter dimensions and will not fit in a typical letter tray.

How do I seal the clasp envelope so it stays closed during transit?

Moisten the deep gumming on the large flap completely, press firmly to seal, then bend the metal clasp prongs flat against the reinforcement for a secure hold.

Will the metal clasp rust if the box is stored in a humid basement?

The clasp is plated for rust resistance, but prolonged exposure to high humidity may eventually cause corrosion on the metal hardware.
