2 x 2 x 37" White Square Mailing Tubes

These 2 x 2 x 37 inch white square mailing tubes are built from ECT-32-B single-wall corrugated board in a one-piece construction that assembles without tape or glue. The square profile is the defining advantage over round tubes — it eliminates rolling on packing tables and conveyor lines, making these easier to handle and stage during high-volume outbound processing.

The 37-inch interior length handles posters, blueprints, architectural drawings, fabric rolls, and banners. E-commerce retailers, print shops, map and document distributors, and architectural firms rely on this format for protecting long, rolled materials during transit without overpacking.

Tubes ship and store flat, reducing warehouse footprint until point of use. The white corrugated exterior presents a clean, professional finish appropriate for both branded and unbranded outbound packaging. Each bundle contains 50 tubes at approximately 0.31 lbs per unit, and ships via parcel carrier.
