These 8 x 4 x 3 inch kraft corrugated mailers are manufactured from ECT-32-B corrugated board and fold from a flat blank into a fully enclosed box, creating double wall protection on the front and sides without tape, glue, or staples. The one-piece construction is the defining feature: no separate sealing supplies are needed at the pack station.

The format suits small, lightweight shipments common in e-commerce fulfillment, subscription box operations, retail distribution, and direct-to-consumer medical or cosmetic product shipping. The interior accommodates items such as lip balm sets, small electronics accessories, sample kits, and similarly compact goods.

Each mailer weighs approximately 0.18 lbs and ships and stores flat to minimize warehouse footprint. The natural kraft finish accepts direct printing and applied labels for branding or compliance marking. Sold in bundles of 50.
