Diameter: Approximately 18 cm This is a retro plate from the 1970s. According to my mother, she used it over 30 years ago. It has been stored in an indoor warehouse without being used for a long time. It's a cool-looking plate made of sturdy glass from the Showa era. It seems to be a good size for serving a single portion of dishes like "bukkake somen" (cold noodles with toppings). (Although the amount of food eaten varies from person to person) I don't see any major damage, but I will list the following points of concern: Image 10 → Marked area, white scratch? present Image 11 → Marked area, rough texture present In addition, there are small scratches overall when held up to the light. I think it can be used without any problems. Please refrain from purchasing if you are concerned about minor details as this is an old product. Thank you to those who understand antiques.
