These 7 x 4 x 3 inch kraft corrugated mailers are built from ECT-32-B single wall corrugated board and use a one-piece fold-together construction that requires no tape, glue, or staples. When folded, the design creates double wall panel reinforcement across the front and sides, delivering crush-resistant protection without added materials or assembly steps.

The self-closing format is well suited to e-commerce fulfillment, subscription box operations, retail distribution, and manufacturing parts shipment — anywhere pack speed and consistency matter. The interior accommodates small hardgoods, media, cosmetics, and similarly sized low-profile products shipped individually or in small quantities.

Each mailer weighs approximately 0.16 lbs and stores flat until needed, keeping shelf and floor space free in high-SKU environments. Sold in bundles of 50; multiple bundles can be ordered to match volume requirements. Ships via parcel carrier.
