This is the Zetland Sqube (Square Postal Tube). This addition to our range is to give you a different option when it comes to mailing.
This design comes to you flat so that you can store more in a smaller space. With a few quick folds you are good to go.
The square sides give it a bit more rigidity than a normal tube protecting you from Royal Mail. These boxes have also been used by architects and drafts men for protecting important documents.
They are 650x70x70mm and made from 3mm thick corrugated board.
