These 10 x 13 inch inter-department envelopes are made from 28 lb kraft paper and engineered for repeated internal mail routing. The string-and-button closure secures contents without tape or adhesive, allowing multiple open-and-reseal cycles throughout the envelope's usable life.

Each envelope is printed on both sides with five labeled columns — Date, Deliver To, Department, Sent By, and Department — accommodating up to 52 routing entries per envelope. This built-in tracking format keeps document flow organized and auditable, eliminating the need for separate routing slips or labels in offices, warehouses, distribution centers, and manufacturing facilities.

Constructed from 28 lb kraft for durability through high-cycle internal routing, the 10 x 13 inch size carries standard letter and legal documents flat without folding. Sold in cases of 100 and ships via parcel carrier.
