This belonged to my parent's collection. They were collected from trips, business trips, and as souvenirs. I think they were purchased about 20-35 years ago. I am not familiar with pottery, so I cannot answer detailed questions. The item with the blue pattern in the last image is the only one of its kind. There are no cracks or chips. Please purchase only if you understand that these items have been stored at home for a long time. I plan to pack them securely and use the Takkyubin (home delivery) service. All packing materials will be recycled. Some materials may show signs of use. Thank you for your understanding.
