This is a set of five Hagi-yaki teacups. I purchased them as a souvenir in Yamaguchi, but I mostly just displayed them after taking them out of the box. The color of the exterior varies depending on the firing process. In the second to last photo, it looks like there are cracks, but I was told that this is how it looked before firing and is nothing to worry about. They are small teacups, but they have a very cute finish. Diameter: Approximately 8cm
