This is a work by sculptor Minami Tada. It was received as a commemorative gift for blood donation. It's a transparent glass sake cup with a distinctive blue bottom. - Color: Transparent/Blue - Shape: Sake cup/Guinomi (small sake cup) - Material: Glass - Size: Approximately 8cm in diameter, 5cm in height It has been stored at home for a long time, but it was taken out of the box for the photos and is unused. I plan to take it out of the box and ship it compactly. Thank you for looking.
