These 5 x 4 x 4 inch kraft corrugated mailers are built from ECT-32-B single wall corrugated board and feature a one-piece self-locking design that folds into a finished mailer in seconds. The corrugated structure creates double walls along the front and sides, adding rigidity and crush resistance without any tape, glue, or staples.
Their compact footprint makes them a practical fit for e-commerce fulfillment centers, subscription box operations, retail distribution, and manufacturing environments shipping small, dense components such as hardware, cosmetics, or promotional items.
Each mailer weighs approximately 0.16 lbs and ships flat for space-efficient storage. Bundles contain 50 mailers, and multiple bundles may be ordered to meet volume requirements. The parcel-friendly format supports high-frequency reorder cycles without special logistics coordination.
