These 5" x 4" x 2" white corrugated mailers are built from ECT-32-B corrugated board and feature a one-piece fold-up construction that locks into place without tape, glue, or staples. The folded structure creates double-wall reinforcement along the front and sides, adding crush resistance where transit stress is highest.

The clean white exterior makes these mailers a practical fit for e-commerce fulfillment, subscription box operations, retail distribution, and direct-mail programs where presentation at the point of delivery matters. At 0.12 lbs per unit, the lightweight build helps manage dimensional weight across high-volume outbound shipments.

Each bundle contains 50 mailers. Interior dimensions measure 5" x 4" x 2", accommodating small components, accessories, cosmetics, and other flat or low-profile items. Orders ship via parcel carrier.
