This is a free cup from Arita's Shin-gama kiln, featuring the Seika (blue flower) design. It's great for wine, plum wine, or sake, but the stylish design also makes it enjoyable to display, and it's never been used. Size: Diameter: 7.1 cm Height: 8.5 cm Bottom Diameter: Approximately 3.8 cm (Approximate measurements) Potter's mark: Seika (blue flower) No original box I believe this is a simple, beautiful piece that will never get old. Please enjoy the beauty of Japanese aesthetics. Thank you very much.
