This item has been stored at home for a long time without being used. The glass has been cleaned and appears to be in good condition. There is a slight stain on the mat, but it's near the edge and barely noticeable. Also, while I can't say for certain there's no color change due to aging, I think it's still beautiful. The size of one side is 28cm high x 23cm wide x 2cm deep. When opened, it requires a space of up to 44cm wide and about 14cm deep. It does not open 180 degrees.
