Phase boxes
A phase box is a protective enclosure whose dimensions and closure depend on the stored form. Record the flap sequence explicitly.
This collection describes enclosure forms, access routes and documentation practices for paper-based material. It is intended for reading and planning, not for directing treatment of fragile objects. Fold diagrams and record examples are original illustrations with no associated collection or accession data. Material descriptions distinguish observed features from documented properties. Decisions about a real object, its condition and its environment require the relevant professional judgement.
Practical example
Keep the object orientation identical across the measuring sketch and folding record.
The term does not certify a material or guarantee long-term preservation.
