Thank you for viewing! This is a ceramic teapot/kettle? and sake set. I don't know how to use it, so please purchase it if you understand from the images. The cups are about 6 cm in diameter, so they are probably ochoko (sake cups). The teapot-like item is flat, so it's probably for otoso (ceremonial sake). I plan to ship via express delivery, so I can't lower the price much. This is a used item, has been stored at home for a long time, and has been inspected by an amateur. I apologize if I missed anything. I recommend that those seeking a perfect item refrain from purchasing. In the past, I have received comments like "There was a stain around ◯◯ and I was disappointed" when receiving feedback. Please consider purchasing only if you understand that this is a used item. m(_ _)m Please check the images for details.
