These 8 x 8 x 4 inch kraft corrugated mailers are one-piece self-locking units built from ECT-32-B single wall corrugated board. No tape, glue, or staples are needed — the fold-over closure creates double wall protection on the front and sides, adding crush resistance during transit without added weight or hardware.

The square format and low-profile depth make these mailers a practical fit for e-commerce fulfillment, retail distribution, and manufacturing outbound shipping. They handle flat goods, folded apparel, accessories, media, and similarly dimensioned products that benefit from a rigid corrugated enclosure rather than a padded envelope or poly mailer.

Each mailer weighs approximately 0.35 lbs and ships flat, keeping storage footprint minimal in warehouse and fulfillment environments. Mailers are sold in bundles of 50 and arrive parcel-friendly, ready for immediate use on packing lines.
