“Giotto” drop spine boxes are made from Duralong Wave archival micro corrugated board, ideal for long term horizontal or vertical storage. The drop spine allows to insert and take out the artefacts in a safe way, and provides a protected micro environment within the box from chemical-physical changes (dust, light, environmental pollutants). Extremely strong and rigid with double thickness walls on all sides of the base and the lid. Quick and easy to assemble thanks to the innovative ultrathin velcro system (1.0 mm approx.). On request it is possible to purchase a handy internal kit (Duralong Special board 1.4 mm and herringbone cotton tying tape) for fixing loose documents, for the safe vertical storage of the artefacts.
