These white easy-fold mailers are built from ECT-32-B single wall corrugated board and feature multiple pre-scored depth lines that let packers adjust the box profile to the product without cutting tools or retooling. The white exterior delivers a clean, professional finish on every panel.

The adjustable depth (1 1/2", 2", 2 1/2", 3 1/2") makes these mailers practical for e-commerce fulfillment centers, direct-to-consumer retail operations, subscription box programs, and medical device distributors shipping products of varying thickness in a single standardized carton. Centering the item, folding at the appropriate score line, and sealing with tape is all that is required — void fill is rarely needed.

Each mailer weighs approximately 0.212 lbs, keeping outbound parcel weight low across high-volume pack-out runs. Sold in bundles of 50 in a flat-pack format that stores compactly on shelving or at packing stations.
