These 3" x 3" x 2" white corrugated mailers are built from ECT-32-B single-wall corrugated board and fold into a finished mailer without tape, glue, or staples. The one-piece self-locking construction assembles in seconds, making it practical for high-volume packing stations where speed and consistency matter.

The white exterior presents cleanly for retail, direct-to-consumer, and subscription box shipments. When assembled, the fold-over construction creates double-wall coverage on the front and sides, adding structural rigidity suited to small cosmetics, jewelry, personal care items, and other lightweight products that require a polished unboxing presentation.

Each mailer weighs approximately 0.06 lbs, keeping actual and dimensional weight costs manageable at volume. Flat blanks store compactly on shelving or in bin systems, maximizing floor space efficiency. Sold in bundles of 50 and ships via parcel carrier.
