[Damage due to aging]. The glass surface looks relatively clean, but there are white speckled stains. This is especially true on the back side. The white speckled stains are hard to see in pictures. But you can see the white speckled patterns when you shine a light on them. We will show you a part of it in the picture. See “red circle” in the picture. There is also a scratch or stain in one place. See “blue circle” in the picture. If you have any question or concern, please do not hesitate to contact me. International Buyers – Please Note.
