These 10 x 13 inch red inter-department envelopes are built for internal mail routing in offices, warehouses, and multi-department facilities. The red color creates immediate visual separation from standard interoffice envelopes, supporting color-coded mail handling workflows without additional labeling.

A string-and-button closure allows secure, repeated use across multiple routing cycles. One side is printed with five columns — Date, Deliver To, Department, Sent By, and Department — providing space for 31 entries per envelope. A single unit can circulate through an organization many times before replacement, reducing per-use material cost.

Envelopes are made from kraft paper stock and sized to accommodate standard letter-size documents, reports, and multi-page materials without folding. Each case contains 100 envelopes and ships via parcel carrier.
