"Lorenzetti" 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). Single walls on three sides of the base and the lid. Easy to assemble thanks to the small self-blocking wings which can be inserted into the wall and practical interlocking system for closing the box.
