Bsc Preferred M3337 Square Corrugated Mailing Tubes 25 Pack

Product Description

The BSC PREFERRED M3337 is a pack of 25 flat-shipping, one-piece square corrugated mailing tubes constructed from 200/ECT-32-B white corrugated material. Unlike round mailing tubes, the square profile prevents rolling during storage, packing, and transit, which reduces handling time and keeps shipments organized on shelves and pallets. Each tube folds together quickly without tape or glue, keeping prep time low in high-volume shipping environments. These tubes ship flat to conserve storage space until needed. The pack weighs 11.7 pounds and the flat-packed unit dimensions measure 46.25 inches long by 17 inches wide by 3 inches tall.

The M3337 square mailing tubes are suited for warehouses, mailrooms, fulfillment centers, and shipping departments that regularly send rolled documents, prints, posters, blueprints, or other tube-packaged items. The square geometry offers a practical advantage in commercial environments where tube storage and stacking density matter. Sold in packs of 25, this SKU is a direct equivalent to part number S-1579, making it a compatible drop-in reorder for operations already using that specification.
