The BSC PREFERRED P3012K is a kraft mailing tube designed for document storage and postal shipment. Built with 3-ply spiral wound construction, these tubes resist crushing and deformation during handling. Each tube ships with white snap-in end caps that secure contents in place without popping off in transit. Sizes listed reflect usable interior space; actual tube length is longer to accommodate the end caps, which add approximately 3 inches. These tubes are reusable and recyclable, making them a practical choice for high-volume mailing or archival storage applications. Sold as a case of 24 units.
These kraft tubes are suited for shipping rolled documents, blueprints, posters, artwork, and similar materials. The snap-fit end caps eliminate the need for separate sealing materials, reducing prep time in mailroom or warehouse environments. The 3-ply wall construction provides structural integrity for both standard mail and courier shipment. The case quantity of 24 supports ongoing document distribution or storage workflows in office, print shop, or facilities management settings.
The P3012K is equivalent to part number S-3614. Designed as a standard-format kraft mailing tube suitable for rolled document storage and postal or courier shipment.
No tools are required to assemble these tubes. Insert rolled documents into the tube, then press the snap-in end caps firmly into each open end until fully seated. For shipment, apply carrier-required labeling to the exterior of the tube. Verify that end caps are fully engaged before handing off to a courier or postal service.
