This is a Kutani-yaki teapot and five teacups. They were used at a Japanese inn and have been stored for about 20 years. They were wrapped in paper and stored in a cardboard box, as there is no original box. They seem a bit small. Please check the images. I think they are in good condition, but this is just my personal opinion. The black spots in the 12th image are present from the beginning. #KutaniYakiTeapotAndTeacups
