This is a celadon teacup with a tea strainer, purchased from a kiln during a trip to Korea several decades ago. I enjoyed displaying it on a shelf without using it, but I've decided to let it go. I will sell it to someone who is interested. Diameter: 7.5cm, diameter of the tea strainer: 5.5cm, height: 9.1cm. Takkyubin (60 size)
