“Arcimboldi” drop spine boxes are made from Duralong Special archival 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). They are supplied ready-assembled with non-rusting metal pins, a small string on the spine for easy handling and a cotton tying tape.
