I don't understand your question Michelle! Why not have the design on both parts, as does the Costebelle one I gave the link to above? (You were the first to reply to my original post on this subject BTW!) In my opinion, it's definitely too large (5" diameter) and heavy to be a trinket box. Not only that, because the outside is smooth and shiny it could easily slip out of your hand. I have come to the conclusion, though I could be wrong, that it is purely decorative and perhaps was made as a graduation piece, but I'd love to hear what others think about that. In the meantime, here are some more pics. (I wish I could find a way of showing the contours on the inside!) Thanks for your interest Michelle (don't you want to look at my nice 'head & shoulders paperweight - maybe I should change the title?)
