These 5" x 2" x 2" white corrugated mailers are built from ECT-32-B corrugated board and fold into a self-locking structure without tape, glue, or staples. When assembled, the design creates double-wall protection along the front and sides, adding crush resistance where the contents are most exposed.

The white exterior finish makes these mailers well suited for direct-to-consumer e-commerce, retail subscription boxes, cosmetics, and specialty food shipments where presentation is as important as protection. Fulfillment centers and boutique shippers alike use them for compact, rigid items that need a clean, professional look at delivery.

Each mailer weighs approximately 0.066 lbs, keeping dimensional weight impact minimal on small-parcel shipments. The one-piece construction also reduces pack-line labor by eliminating separate closure steps. Mailers are sold in bundles of 50 and ship via parcel carrier.
