These 4" x 4" x 4" inch white corrugated mailers are built from ECT-32-B s corrugated board and feature a one-piece fold-lock design that closes without tape, glue, or staples. Assembly creates double-wall reinforcement along the front and side panels, adding crush resistance at the points most vulnerable during transit.

The clean white exterior makes these mailers well-suited for branded and unbranded outbound shipments in e-commerce fulfillment, cosmetics, specialty retail, and subscription box operations. Their compact cube format is particularly effective for small, dense items where a snug enclosure reduces interior movement.

Interior dimensions are 4" L x 4" W x 4" H. Each unit weighs approximately 0.14 lbs, supporting efficient dimensional weight management. Sold in bundles of 50 and ships via parcel carrier.
