These 3 x 3 x 2 inch kraft corrugated mailers are built from ECT-32-B single wall corrugated board and use a one-piece fold-together design that requires no tape, glue, or staples. When assembled, the construction produces double walls on the front and sides, adding structural rigidity without any additional materials or steps.

The compact format suits small-item shipments across e-commerce fulfillment, cosmetics, jewelry, specialty retail, and light industrial parts distribution. At 0.07 lbs, each mailer contributes minimal dimensional weight, making them practical for high-volume outbound operations where per-shipment costs are closely managed.

Each mailer ships and stores flat, keeping warehouse footprint low until units are needed at the packing station. Sold in bundles of 50, parcel-friendly for routine restocking.
