Diameter: 8.5cm Depth: 9cm This is a set of two Gudetama mugs. (The pattern is the same on both) They are a bit deep and have a large capacity, so you can relax with Gudetama. They have been used a few times and stored. One of the cups has a small black mark on the inside. It was there from the time of purchase (photo 7). Please understand this before purchasing.
