Square Mailing Tubes

White Square Mail Tubes

These Square Mailing Tubes have a standard square shape, that makes inserting and removing contents easy. They are ideal for the storage or mailing of documents, blueprints, etc. Our Mailing tubes are made from strong 200#-B oyster white corrugated cardboard. They ship and store flat to save on both shipping and warehouse space and are constructed with Locking tabs that require no tape when assembeling the square tube.
