Type: Rock glass Material: Glass Size: Small (Diameter: approx. 8cm, Height: approx. 9.5cm) This is a genuine rock glass from the Showa era. It has thick glass and a substantial weight. Perhaps due to the age of the glass, or maybe because it's thick, the transparency doesn't seem to be as high as modern glasses. I have carefully stored it in my home cupboard. Although unused, it has been stored at home for a long time, so please understand this before purchasing. Also, the shipping method is set to Rakuraku Mercari Bin, but it may be changed to Yu-Yu Mercari Bin depending on the packaging. Please be aware of this.
