● These are old glass parts made in Izumi City, Osaka Prefecture. ● The frosted glass-like pieces have a convex surface on both sides. ● I have cleaned them, but as they are old, there may be scratches, cloudiness, and dirt. ● I still have several in stock, so please inquire if you would like multiple pieces. The price for the second piece onwards is 400 yen each (200 yen off).
