I'm not sure what type of pottery it is, but it's a tea bowl for practice. No box. It is a used item. This item was stored at my grandfather's home for a long time. There are changes in the texture due to aging, but there is no noticeable damage. Please purchase only if you understand that it is a used item. Due to amateur inspection, there may be small oversights. Please check the condition in the images. If you have any concerns or anxieties, please refrain from purchasing. This item is stored at home. I am also listing it on other sites, so I may remove the listing without notice. Thank you for your understanding.
