This is a set of original Yoshio Yoake mugs. It was a novelty item from Chuo Mitsui Trust Bank. It is new and unused, having been stored in a closet, but I am selling it because I have no opportunity to use it. Made by Narumi, so it is a sturdy product. The mugs are new and clean, but the box has some deterioration due to the passage of time. Please refrain from purchasing if you are looking for a perfect new item. Size: Height approx. 6.7cm, Diameter approx. 8.3cm
