The cup's mouth diameter is about 5.5 cm, and its height is about 5 cm. The length from the pot's spout to the handle is about 16 cm. The diameter is about 6 cm, and the height is about 7 cm. It's cute and heartwarming to stack the three pieces together. I think it would also be a great gift. Unused. Although unused, I didn't mark it as new because it has been stored for a long time. I will pack it carefully to prevent breakage.
