Unused. Kutani-yaki, Yuji Kiln, Kiyohide. Kin-sai Aotsubu Tessan, Covered Tea Set. Kutani-yaki is characterized by the use of "gosu," a cobalt blue pigment, for outlining, and the "gosai" method, which involves applying thick layers of paint in five colors: red, yellow, green, purple, and indigo blue. Although unused, it has been stored at home for over 30 years, so the wooden box has deteriorated and has some cracks. Please understand this before purchasing. #KutaniYaki #CoveredTeaSet
