The BSC PREFERRED EN1010 is a reinforced clasp envelope built for repeated use in high-volume mailroom and office environments. Each envelope features a metal clasp closure that allows the flap to be opened and re-secured multiple times without damage. A gummed flap provides a permanent seal when moistened and pressed closed, giving users the option of a final, tamper-resistant closure when needed. Constructed from a strong 28 lb woven stock, these envelopes resist tearing under the load of dense documents, small parts, or multi-page submissions. The case contains 500 envelopes, making it suited for facilities, warehouses, and offices with consistent mailing demands.
These clasp envelopes are used in general office, mailroom, administrative, and light industrial settings where documents need to be routed internally or mailed externally with the ability to reopen and reseal. Typical applications include routing paperwork between departments, submitting multi-page reports, and organizing field service records. The dual-closure design - metal clasp plus gummed flap - accommodates both temporary internal routing and final outbound mailing without swapping envelope types. They are sold by the case for facilities purchasing.
Designed as a standard clasp-and-gummed-flap envelope suitable for general mailroom, office routing, and outbound mailing applications.
No tools are required for use. To activate the gummed flap seal, lightly moisten the adhesive strip and press firmly for several seconds. Do not over-moisten, as excess moisture can weaken the adhesive bond. Store unused envelopes flat in a cool, dry location to preserve gum adhesion and prevent warping of the woven stock.
