“Fattori” tube boxes are made from Duralong Wave archival micro corrugated board, with internal suspended support, made from Duralong PaperPhoto conservation paper, ideal for long-term horizontal storage. Thanks to their square shape they can be easily stored horizontally; the practical internal support avoids the flattening of the artefacts. They allow access to contents without removal from the stack, through the front opening. The closure of the box is secured by two side caps with a central hole, one fixes with very thin Velcro (approx.. 1.0 mm), the other with tabs.
