This is a set of two soup cups. The approximate measurements, taken by an amateur, are: diameter of the opening is about 11 cm, and height is about 6 cm. I've used them a few times since I bought them, but I don't use them often, so I'm selling them. The yellow cup has some color unevenness from the time of purchase (see photo 4). There don't seem to be any other noticeable stains or scratches, but please refrain from purchasing if you are looking for a perfect item. No returns accepted.
