These 5" x 4" x 4" inch white corrugated mailers are built from ECT-32-B corrugated board and assemble without tape, glue, or staples. The one-piece fold design locks closed in seconds, and the fold pattern naturally creates double-wall panels along the front and sides for added crush resistance during transit.

The clean white exterior makes these mailers a practical fit for e-commerce outbound orders, subscription box fulfillment, retail replenishment, and any operation where presentation at the doorstep matters. At 0.17 lbs per unit, they keep shipping weight low — a meaningful factor for high-volume shippers managing per-unit postage costs.

Interior dimensions measure 5" L x 4" W x 4" H. Each bundle contains 50 mailers and ships via parcel carrier, making routine restocking simple for facilities at any volume.
