Archival Methods Onyx Portfolio Boxes are often the best choice where presentation is as important a factor as storage and protection. This is particularly applicable for photographs, prints and similar art work that are in what we might call live storage, regularly presented or viewed but safely housed in between.
Portfolio boxes have the appeal of being "lockers" that converts to a "stage." Ruggedly constructed and well sealed, Archival Methods portfolio boxes flip open to provide a handsome, complimentary background that enhances and frames the contained works.
