These 2 1/2 inch inside diameter white mailing tubes feature 3-ply spiral wound construction with a .07" wall thickness, delivering the structural rigidity needed to protect rolled documents, drawings, blueprints, and similar cylindrical contents from crushing or deforming in transit. White snap-on end caps are included with every tube and are engineered to hold securely without popping off during shipment.

The 30" measurement reflects usable interior space — actual tube length is slightly longer to accommodate the end caps. These tubes are well suited for architectural and engineering firms shipping large-format drawings, print studios fulfilling poster orders, legal offices mailing rolled documents, and photography or fine art operations packaging prints for clients.

Tubes are reusable and recyclable, and replacement 2 1/2" end caps are available separately for multi-use or return-shipping programs. Each case contains 34 tubes and ships via parcel carrier.
