Zoro Select MRX5X Literature Mailer White 50 Pack

White corrugated mailers for bulk shipping

This pack contains 50 literature mailers made from single-wall B-flute corrugated cardboard in white. Each box measures 6 1/2 x 4 1/2 x 2 1/2 inches inside and out with a 3/16 inch wall thickness. They are rated ECT-32-B with a maximum load capacity of 65 lb and are 100 percent post-consumer recyclable. The flat-shipping design assembles quickly for high-volume fulfilment.

Suited for flat media and light goods

These mailers fit books, catalogues, documents and similar flat items that need rigid protection in transit. They are not designed for heavy, dense or irregularly shaped products that exceed the 65 lb limit or require double-wall construction. Buyers who need larger internal dimensions or higher crush resistance should look at a different box style.

Capacity and headroom for daily fulfilment

The 50-count pack supports extended mailing runs without frequent re-ordering. Each unit handles loads up to 65 lb, giving headroom for multiple books or thick brochures in a single shipment. Very heavy items or oversized literature that surpass the internal volume will require a larger mailer.
