Yoshizawa Kiln pottery. I purchased it from the official online shop several years ago. After using it a few times, I haven't used it much, so I've been storing it. Please refrain from purchasing if you are concerned about minor scratches, etc., as it is a home-stored item. It is relatively clean, but as it is a used item, please refrain from purchasing if you are nervous about it. We will use recycled materials (reused cardboard, etc.) for packaging and shipping. Thank you for looking.
