These 7 x 7 x 2 inch white literature mailers are built from ECT-32-B single wall corrugated board, delivering a rigid, protective enclosure with a clean white exterior suited for customer-facing shipments without additional finishing.

The self-locking tab closure seats firmly without tape, glue, or tools, cutting pack station time and eliminating closure consumables. The square footprint fits standard document sizes, promotional inserts, printed media, and similarly dimensioned flat goods — making these mailers practical for e-commerce fulfillment, retail distribution, and direct mail operations.

Mailers ship flat and are sold in bundles of 50, sized for easy storage at pack stations and consistent replenishment in higher-volume environments.
