These 3 x 3 x 37 inch kraft square mailing tubes are built from ECT-32-B corrugated board, delivering crush resistance and structural rigidity for long, slender shipments. The square profile is the key differentiator here: unlike round tubes, it stays put on pack lines, conveyor belts, and staging surfaces without rolling or shifting.
The 37-inch interior length and compact 3 x 3 inch cross-section make these tubes well suited for posters, blueprints, fabric bolts, curtain rods, fishing rods, and architectural drawings. E-commerce fulfillment centers, print shops, craft suppliers, and industrial distributors rely on this format for protective, professional-looking outbound packaging.
Each tube ships flat and assembles without tape or glue, keeping storage footprint minimal and packing speed high. Units weigh approximately 0.44 lbs each. Bundles contain 25 tubes and ship via parcel carrier.
