Although unused, there is a note on the box. I hope you understand that this is only for product protection. Also, the teapot and teacups have been taken out for photography. This is a long-term storage item. Although it has not been used, it is still an opened item. The height of the pot (excluding the lid) is about 10.5cm, the cup's diameter is about 7cm, and the height is about 6.5cm.
