This is a Yumiko Iihoshi mug I purchased at a directly-managed store several years ago. It's the Enju series in pink. I've used it about 5 times and have kept it stored at home. Diameter: Approximately 9.5 cm Height: Approximately 7 cm There are no noticeable stains, but please understand that this is a used item before purchasing. It will be shipped in a box.
