3 x 3 x 25" Kraft Square Mailing Tubes

These 3 x 3 x 25 inch kraft square mailing tubes are built from ECT-32-B corrugated board, delivering rigid structural support for posters, rolled prints, architectural drawings, banners, and other elongated items that require enclosed protection during shipping. The square design eliminates rolling during handling and transit, and stacks more reliably than round tube formats.

Print shops, e-commerce retailers, architectural firms, and manufacturing operations shipping rod-shaped or rolled goods all benefit from the consistent sizing and stable form factor. The flat exterior surface accepts standard shipping labels and direct address printing without additional preparation, keeping fulfillment workflows clean and efficient.

Each tube is constructed to fold into final form without tape, glue, or additional fasteners, and ships flat to reduce warehouse storage footprint. At approximately 0.312 lbs per unit, they add minimal weight to outbound shipments. Sold in bundles of 25, supporting consistent pick-and-pack volume across repeat orders.
