Esselte's mailing tubes are a practical solution for the secure dispatch and archiving of documents and other flat items. Made from sturdy, white corrugated cardboard, these sleeves offer a space-saving and stackable way to organise your items efficiently. With a square cross-section and a length of 750 mm, they are ideal for mailing. The mailing tubes can also be labelled, making it easy to identify the contents. Their robust design ensures that the contents are well protected during transport. These folding tubes are not only functional, but also environmentally friendly as they are made from FSC-certified material.
