3 x 3 x 43" White Square Mailing Tubes

These 3 x 3 x 43 inch white square mailing tubes are built from ECT-32-B white corrugated board and form quickly without tape or glue. The square profile is the key differentiator: it prevents the tube from rolling during handling and staging, making management on packing lines noticeably easier than with round alternatives.

At 43 inches long, these tubes fit posters, blueprints, banners, architectural drawings, fabric rolls, and similar long rolled goods. Print shops, fulfillment centers, retail distributors, and architectural firms are typical users, particularly where a clean white exterior matters for direct-to-consumer or retail-channel presentation.

Each tube weighs approximately 0.63 lbs. The flat-ship construction reduces warehouse storage footprint until tubes are needed. Tubes are sold in bundles of 25 and ship via parcel carrier.
