Set of 4 Ko-Kutani ceramic teacups in various colors. A rare set of Ko-Kutani teacups. I believe these can be used for tea, coffee, etc. They are about 9cm tall and are sturdy. They are quite old, so there are some stains and scratches, but they have been carefully stored. Thank you. - Colors: Black, White, Blue, Brown - Material: Ceramic - Bottom Mark: Handwritten signature - Shape: Cylindrical - Quantity: Set of 4
