The heavy-duty Jakar Teletube Giant is a practical way to store large posters, artworks, maps and other documents. They're made from strong black plastic, and have a secure lid, as well as a shoulder strap to make them easy and comfortable to transport. The length of the tube is adjustable, so you can expand it when you want to store something really huge, but close it back down again when you don't need so much space. The Jakar Teletube Giant extends from 71.5cm to 123cm, with an internal diameter of 7.5cm. The Jakar Teletube Jumbo extends from 69cm to 123cm, with an internal diameter of 10.5cm.
