Glass tableware from the Showa era. It's a beautiful blue glass, and I think the third image is the closest to the actual color. I'm not sure if I can describe it well, but it's shaped like a goldfish bowl. I used it a few times in the past, but it's been sitting in the cupboard. It had a dullness from aging, but I washed it with dish soap and soaked it in kitchen bleach, and the smooth transparency returned. The width at the top is about 10cm, and the height is about 5cm. #FruitPlate #DessertPlate #ShowaRetro
