Yellow inter-department envelopes in a 10 x 13 inch format are built for multi-cycle internal routing. The yellow stock provides immediate visual contrast in mixed mail streams, allowing mail room staff to sort and prioritize without reading each piece individually. The string-and-button closure seals securely and reopens cleanly through repeated delivery cycles, reducing per-use cost compared to single-use envelopes.

These envelopes are well suited to corporate mail rooms, hospital systems, university campuses, government offices, and any multi-building operation routing documents between departments on a recurring basis. The 10 x 13 inch opening accepts unfolded letter-size documents, multi-page reports, and flat forms without bending or cramming.

Each envelope is printed on one side with a five-column routing grid — Date, Deliver To, Department, Sent By, and Department — with space for 31 entries, giving each envelope a long usable lifespan before replacement. Cases contain 100 envelopes and ship via parcel carrier.
