These 3 x 30 1/4 inch white triangle mailing tubes are built from ECT-32-B white corrugated board and ship flat to minimize storage footprint until assembly is needed. Each tube folds along pre-scored lines and locks into shape using integrated tabs — no tape, glue, or additional fastening materials required.

The triangular profile opens along the full length of the tube, making loading and unloading faster than with traditional round tubes. This design suits e-commerce fulfillment, retail distribution, print and poster shipments, document handling, and manufacturing environments where rolled or elongated items require protected transit. The triangle shape does not roll around in transit like traditional round tubes.

Each assembled tube weighs approximately 0.53 lbs. The white exterior surface accepts direct labeling and works with standard shipping workflows. Tubes are sold in bundles of 50 and ship via parcel carrier.
