“Annigoni” boxes with double-flap lid are made from Duralong Wave archival micro corrugated board, ideal for long-term horizontal or vertical storage. The doubleflap opening is practical and quick and is facilitated by a herringbone cotton tape, while the closure is ensured by two strong magnets. The boxes are entirely self-assembly and are fitted with tabs and a very thin velcro (1.0 mm approx.), already mounted on the walls.
