12 1/8 x 9 1/8 x 4" White Easy-Fold Mailers

These white easy-fold mailers are manufactured from ECT-32-B single wall corrugated board and arrive pre-scored at multiple depths, allowing packers to fold to the required height and seal with tape — no cutting or additional tooling required. The white exterior delivers a clean, professional presentation that holds up through transit.

The multi-depth scoring (1/2", 3", 3 1/2", 4") makes these mailers well-suited for e-commerce fulfillment, retail distribution, direct mail, and B2B shipments where product thickness varies across orders. By adjusting fold depth at pack time, a single mailer size accommodates a range of low-profile items without requiring multiple SKUs on the shelf.

Constructed to ECT-32-B specification, each mailer weighs approximately 0.33 lbs, adding minimal weight to outbound shipments. Bundles contain 50 mailers and ship via parcel carrier, supporting efficient replenishment for warehouses and fulfillment operations at any volume.
