I have been playing with printing a colorful pattern on heavy cardboard and then cutting out the box 
A light score would suffice, so I had not been thinking living hinge, but that sets some ideas as well. even just a series of scores would work for cardboard.
An artist friend who sells a lot of her stuff in Japan mentioned the need for a quality “presentation box” that I would have thought of as a piece of art in itself, but she had said that none of her work would sell if the box was not a part of it, and the quality of the box needed to reflect what was inside.
