These 12 x 11 1/2 x 3 inch white easy-fold mailers are built from ECT-32-B single wall corrugated board and scored at multiple depths (1 1/2", 2", 2 1/2", 3"), allowing the finished box height to be adjusted to match the actual thickness of the contents. Assembly requires no glue or machinery — fold the sides inward at the desired score line and seal with tape.

The bright white exterior makes these mailers a practical fit for e-commerce fulfillment, retail direct-mail programs, subscription box operations, and any application where presentation at the point of unboxing matters. The adjustable depth also reduces wasted interior space, which helps control dimensional weight costs in high-volume shipping environments.

Each mailer weighs approximately 0.34 lbs, and the product is parcel-friendly for efficient replenishment. Bundled in quantities of 50, making it easy to manage inventory against consistent order volumes.
