I don't know much about the item. It's a thin, pleasant-to-the-touch vessel. I'm not sure if it's a tea ceremony utensil. I apologize. There are also some stains due to long-term storage, but I think it's better not to wash it, so I will ship it as is. Although it has never been used, I will list it as "close to unused." Please understand that this is an old, used item and I welcome those who are interested. There are no smokers in the house, but we do have a cat. If you are concerned, please refrain from purchasing. For shipping, I will use used materials such as cardboard boxes and packing materials. Thank you for your understanding and consideration!
