This is a set of Kutani-yaki sake ware, including a tokkuri (sake bottle) and two ochoko (sake cups). This sake ware is decorated with black lines of gos (a cobalt pigment), and the "Kutani Gosai" technique is used, which involves applying thick layers of pigments in five colors: dark blue, green, yellow, and others. It has been stored in the storage room of my parents' house for a long time. Thank you. #KutaniYaki #SakeWareSet #ShowaRetro #Vintage
