These 4 x 4 x 28 inch tall corrugated boxes are built from ECT-32 kraft single wall corrugated board, delivering a narrow, rigid upright container with an end-loading design that allows quick insertion and secure closure without repositioning contents.

The interior footprint serves as a practical alternative to mailing tubes, offering structural rigidity that film-based tubes cannot provide. E-commerce fulfillment centers, retail distributors, and manufacturers rely on this profile for posters, dowels, curtain rods, long-handle tools, fishing rods, and similar elongated products that demand a rigid, form-fitting enclosure.

Boxes are sold in bundles of 25 and ship flat to minimize storage footprint. ECT-32 construction meets standard single wall performance requirements for parcel shipments. Ships via parcel carrier.
