This appears to be a demitasse cup and saucer from Matsumine Kiln. It was found while organizing a friend's house after they moved. I don't know the details, such as when or where it was purchased. It has been washed before listing. I am not a professional, so I may have missed some dirt. Please refer to the images for the size. (There may be some slight variations) I am also listing many other items. (Please note that I may not be able to combine shipping due to shipping costs and packaging.) Thank you for looking.
