12 x 4 x 2" Kraft Corrugated Mailers

These 12 x 4 x 2 inch kraft corrugated mailers are built from ECT-32-B single wall corrugated board and fold into a double walled box structure using a self-locking one-piece design — no tape, glue, or staples required at any point during assembly.

The slim 2" depth makes these mailers well-suited for e-commerce fulfillment, direct mail campaigns, retail distribution, and subscription box operations shipping flat or low-profile products such as documents, photos, small apparel items, and thin accessories.

Each mailer ships and stores flat, reducing warehouse footprint between uses. Individual mailers weigh approximately 0.20 lbs, supporting efficient dimensional weight management on small-parcel shipments. Sold in bundles of 50, with a natural kraft finish that presents cleanly without additional surface treatment.
