Thank you for viewing. I bought this at an antique market, and was told it was a teacup from the Meiji or Taisho era. The rim has a wavy design, giving it an antique feel. - Color: Blue - Shape: Round - Material: Ceramic - Size: Approximately 7cm in diameter, 5.8cm in height As it is an antique, I have been displaying it at home. There are no documents to prove its authenticity. Please consider this before purchasing. I will use either Yu-Yu Mercari Bin or Rakuraku Mercari Bin for shipping. It will be sent with simple packaging. If you have any questions, please feel free to ask before purchasing.
