The QUALITY PARK QUA38734 is a red clasp envelope measuring 9 inches by 12 inches, sold in a pack of 10. It features a reinforced metal clasp closure and deep gumming along the flap for a secure double-closure seal. The bright red color makes these envelopes well suited for high-visibility mailings where documents need to stand out. Each envelope is designed to hold standard letter-size documents, reports, contracts, and flat materials up to 12 inches in length. Office staff, mail room personnel, and administrative professionals typically handle these for internal routing or outbound document delivery.
These envelopes are used in office, commercial, and light industrial environments where secure document transport and visual identification are priorities. The 9-by-12-inch format accommodates unfolded letter-size paper, booklets, catalogs, and flat media without bending. The red color is commonly used for priority routing, interoffice coding, or client-facing mailings that require immediate visual attention. Each pack contains 10 envelopes. The reinforced clasp allows the envelope to be opened and reclosed multiple times, supporting reuse in interoffice routing applications.
Designed as a standard 9-by-12-inch clasp envelope suitable for use with letter-size documents, flat printed materials, and similar contents requiring a secure, reclosable mailer.
No tools or trade licensing are required to use these envelopes. When using the gummed flap for permanent closure, ensure the flap adhesive strip is fully moistened before pressing to achieve a complete seal. For interoffice routing using only the clasp, avoid overfilling the envelope beyond its rated flat capacity to prevent clasp stress. Store unused envelopes flat in a dry environment to preserve the gum adhesive.
