This is a ceramic yunomi (teacup). It's a large size, so I think it can also be used as a coffee cup. I don't know what type of ware it is, so I won't specify. 【Size】 Diameter: Approximately 9 cm Height: 6 cm 【Please Note】 Although it is a new, unused item, the condition is listed as "New, Unused" because it has been stored in a warehouse for many years and is not from the last few years. Therefore, the subject is listed as "Unused Item." Please understand this point when purchasing. There are individual differences in how dirt and scratches are perceived, so please also check the photos. If you have any concerns about your purchase, please contact us in advance. If you have any questions, please feel free to ask.
