This is a set of 5 special Japanese Go Association (Nihon Ki-in) teacups. Unused. Diameter: 6.3cm Height: 9cm (Please allow for slight variations due to amateur measurements) The "Shinogi no Kishu" (Life-and-Death Technique) teacup has a stain on the lower part. I believe this is due to aging. (See photo 9) Other than that, I don't think there are any scratches or stains, but please forgive any oversight of minor details. These have been stored at home for a long time, so please consider this before purchasing. Thank you for looking.
