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

These 12 1/8 x 9 1/8 x 1 inch white easy-fold mailers are built from ECT-32-B single wall corrugated board, delivering rigid structural protection that poly mailers and padded envelopes cannot match. The adjustable depth (1/2", 1") keeps dimensional weight low while maintaining a clean, professional white exterior finish.

The pre-scored design allows users to fold sides inward at the depth that best fits the contents and seal with tape — no cutting tools required. That makes these mailers well suited for direct-to-consumer e-commerce operations, subscription box fulfillment, retail distribution centers, and any packing environment where flat or low-profile items move at high volume.

Each mailer weighs approximately 0.22 lbs. Bundles contain 50 mailers and ship via parcel carrier, keeping replenishment simple for both low- and high-volume operations.
