These 5" x 3" x 3" white corrugated mailers are built from ECT-32-B corrugated board and fold into a secure enclosure without tape, glue, or staples. The one-piece construction locks together in seconds, eliminating assembly hardware and reducing per-shipment packing time.

The fold design creates double-wall panel reinforcement along the front and sides — the zones most exposed to transit impact. This makes them well-suited for e-commerce fulfillment centers, subscription box operations, retail distribution, and any environment shipping small, rigid, or fragile items at volume.

Each mailer weighs approximately 0.12 lbs, keeping dimensional weight impact minimal on small-parcel outbound shipments. The white exterior finish presents cleanly without additional wrapping. Bundles of 50 ship via parcel carrier and store compactly on standard warehouse shelving.
