Product identity

Business Source 36666 clasp envelopes measure 10 by 15 inches and use 28 lb Kraft paper. The box contains 100 heavy-duty envelopes with metal clasps and deep gumming on large flaps. They are designed for offices that need durable, reusable mailing or storage envelopes.

Who it suits and who it does not

Suits teams sending thick document bundles, catalogues or samples that require a strong clasp closure. Not suited for buyers who need peel-and-seal convenience, window envelopes for addressing, or lighter-weight envelopes for high-volume postage savings.

Installation and common issues

No installation is required; simply insert contents, fold the flap and secure the metal clasp or moisten the gummed seal. Issues sometimes arise if the clasp prongs catch on adjacent envelopes in storage or if the gumming dries out in very low humidity.

Questions about this item

What size documents fit inside the 10 by 15 inch envelope?

Documents up to 10 by 15 inches fit flat inside the open-end style envelope.

Can the metal clasp be reused many times without bending?

The plated metal clasp has rounded edges for rust resistance and repeated opening and closing.

How do I know the 28 lb flap gumming has sealed properly?

Press the large flap firmly; the deep gumming creates a strong bond that holds the envelope closed.
