• Mailing tubes are an excellent way to ship artwork, maps blueprints, posters, and any other large documents that you do not want to fold.
• We stock round, square, rectangular, and triangular shapes and can custom-design nearly any shape to fit.

How to measure:

• Mailing tubes are measured in terms of usable space – the inside diameter and the length minus the thickness of the end caps.
• To find the outside diameter of the shipping tube, add two times the thickness of the tube to the inner diameter.
• To find the actual length of the mailing tube, add the thickness of the two caps to the inside length.
