Thank you for viewing. This is a Hagi-yaki kyusu (teapot). Hagi-yaki is characterized by its soft clay with little vitrification, its absorbency, and the changes over time known as "Hagi's seven transformations." There is some staining on the lid due to aging. Please check the 5th and 6th images. Diameter (outside): 11cm Height: 8cm Handle length: 6cm Capacity: 350ml Thank you. #Hagiyaki #Kyusu (Teapot)
