Posting this for my sister. Looks kinda like an eye glass case to me
Here is another mystery item for you. It’s made of wood covered with shagreen and copper trim.
I’m not sure what it was used for but I use it for keeping my pens for drawing in.
By doing a Google image search for “antique shagreen case” I was able to find several similar to this one. The consensus seems to be that they are 19th century spectacle cases. I saw a site or two note them as being “Chinese” also.
