These 4-1/2 x 5-1/2 inch orange packing list envelopes feature a printed "Packing List/Invoice Enclosed" legend and a high-contrast color that makes document pouches immediately identifiable by warehouse staff, carriers, and receiving personnel. The self-adhesive closure holds documents securely against the outside of any outbound package throughout transit.

The side-opening design — along the 4-1/2 inch dimension — accommodates standard folded invoices, packing slips, and customs paperwork without refolding. The orange color differentiates these pouches from clear or white alternatives, a practical advantage in operations routing multiple document types across outbound shipments in fulfillment, distribution, and manufacturing environments.

Each case contains 1,000 envelopes, providing the volume needed for high-throughput shipping departments. The exterior dimensions are 4-1/2 x 5-1/2 inches, and the parcel-friendly case size supports routine replenishment ordering without coordinating large freight quantities.
