The blue/gray 30.1" Triangular Roll Storage Boxes from Archival Methods come in a pack of 3 and are made of archival-quality E-flute corrugated material. They provide safe, acid- and lignin-free storage of maps, prints, and drawings. Each triangular box opens fully along the long side, allowing for safe placement and removal of rolled items. The 6” sides of the triangle will hold a roll with a diameter of 3.5”.

Rolled items can get damaged in the process of storage. The triangular shape of these boxes prevents the damage caused by pulling on the edges of the rolled items while removing them. The triangular design also reduces the possibility of causing wrinkles when handling the rolled items.
