Arita-yaki, Fukagawa Seiji, teacups. I believe this is a rather old design. Although it is a new, unused item, please note that there is a small chip on the rim (as seen in the 4th image) and several pinholes inside. Only those who understand this are welcome to purchase. It can also be used as a sobachoko (small bowl for soba noodles).
