These 5 x 5 x 3  kraft corrugated mailers are built from ECT-32-B single wall corrugated board and assemble without tape, glue, or staples. The one-piece construction folds into a double walled structure along the front and sides, providing crush-resistant protection while keeping the packing process fast and consumable-free.

The flat-pack format suits high-density warehouse shelving and e-commerce fulfillment operations where storage space is limited. Their compact interior dimensions make them a practical fit for cosmetics, jewelry, small electronics accessories, promotional items, and subscription box components that ship in small, cube-shaped parcels.

Each mailer weighs approximately 0.15 lbs, helping manage dimensional weight on small parcel shipments. The mailers are parcel-friendly and sold in bundles of 50.
