These 3 x 3 x 18 inch kraft square mailing tubes are built from ECT-32-B corrugated board, delivering rigid, crush-resistant protection for long, narrow items. The square profile is the key differentiator: unlike round tubes, these won't roll on conveyor belts, sorting surfaces, or shelving, making them easier to process at every stage of handling.
They're well-suited for e-commerce fulfillment, retail distribution, print shops, architectural firms, and blueprint services — anywhere documents, posters, prints, rods, or similarly dimensioned goods need reliable transit protection. The 18" length accommodates standard rolled prints and tube-format merchandise without trimming or overhang.
Constructed from ECT-32-B single-wall corrugated kraft, each tube ships flat to conserve storage space and folds together without tape, glue, or additional materials, cutting pack-station labor. Each unit weighs approximately 0.14 lbs. Sold in bundles of 25.
