These kraft adjustable mailing tubes measure 3 1/4" diameter and telescope from 24" to 44" in length through a 2-piece sliding design. At .180" wall thickness, the tube delivers heavy-duty rigidity suited to contents that thin-wall tubes cannot reliably protect — rolled documents, architectural drawings, rigid artwork, and similarly elongated items.

The telescoping inner tube slides and locks at the required length, making this format practical for operations shipping variable-length items across different orders without maintaining multiple fixed-length SKUs. Pre-attached end caps are included with every tube, eliminating a separate cap sourcing step and accelerating pack-out. Industries such as engineering, printing, retail, and manufacturing use these tubes regularly for both outbound shipment and internal document storage.

Kraft construction keeps unit weight low relative to wall strength. Listed length range reflects usable interior; the actual tube is slightly longer to accommodate the end caps. Each case contains 25 tubes and ships via parcel carrier.
