Cut Glass Salad Bowl, approximately 8mm thick. This item has been used for over 50 years, and there are some scratches on the cut edges of the rim. Although there are scratches, we in my family didn't mind them when using it. Please be aware of this. The glass is thick and the cutting is of high quality, I believe. I think it's probably Czech cut glass. I remember it cost tens of thousands of yen when I bought it.
