These 5" x 4" x 3" inch white corrugated mailers are built from ECT-32-B corrugated board, delivering crush resistance without excess bulk. The one-piece fold-lock design assembles in seconds with no tape, glue, or staples — making them efficient for high-volume packing lines. Double-wall paneling on the front and sides adds structural rigidity where transit stress is highest.

The clean white exterior accepts direct labeling or branded inserts without additional preparation, making these mailers a practical fit for e-commerce fulfillment centers, subscription box operations, retail replenishment programs, and pharmaceutical sample distribution. Their compact footprint suits products such as cosmetics, small electronics accessories, jewelry, and folded apparel.

Each mailer weighs approximately 0.13 lbs and ships via parcel carrier. Bundles of 50 allow flexible stocking for both low-volume and high-throughput operations. Multiple bundles can be ordered together to meet larger demand without minimum quantity restrictions.
