These are Elmo and Cookie Monster mugs purchased a few years ago at Universal Studios Japan. They are sold as a set of two. They have only been used once or twice and are in beautiful condition (^-^) They are large cups, so they can hold a lot of liquid♪ As shown in the fifth photo, there is a black mark on the bottom of the Elmo mug, which was there originally and could not be removed even after scrubbing several times. Type: Mug Material: Ceramic Diameter: 8cm
