This is from the Ceramic Ai Kyo-Kiku series, which I was collecting. Although they are unused, they have been stored in a box for a while, so I think of them as used items. As shown in the last photo, there is a small stain on one of the teacups. I think it's a very calm and elegant pattern. Coffee Cup Diameter: Approximately 7.2 cm Height: Approximately 7 cm Saucer: Approximately 13.8 cm Teacup Diameter: Approximately 8.8 cm Please note that these measurements are approximate due to amateur measurement.
