This is a photo frame (inner dimensions 9 x 13 cm) from Christofle, a long-established French silver manufacturer. Although it is unused, it has been stored for a long time. Upon listing, I took it out of the box and removed the back to check for any deterioration inside the frame. Upon close inspection, there are some areas inside that are slightly rusty, and the glass is also becoming cloudy. It might be possible to clean it with glass cleaner, but I'm not sure. Please understand that this is a long-term storage item and accept the aging process before purchasing. Please refrain from purchasing if you are concerned about minor details.
