These 8 x 4 x 3 inch white corrugated mailers are built from ECT-32-B single wall corrugated board and fold into a finished mailer in seconds using a one-piece self-locking design — no tape, glue, or staples required. The white exterior delivers a clean, professional appearance suited for direct-to-consumer shipments and branded inserts.

The folded structure creates double wall panels along the front and sides, adding rigidity and impact resistance where small parcels are most vulnerable during transit. At approximately 0.17 lbs, the lightweight construction helps control dimensional weight costs for e-commerce fulfillment, retail replenishment, subscription box operations, and warehouse outbound lines handling compact, lightweight products.

Each bundle contains 50 mailers. Interior dimensions make these mailers well-matched to small products such as cosmetics, electronics accessories, and folded apparel. The parcel-friendly size allows direct integration into standard carrier workflows without additional packaging steps.
