This item is over 10 years old, but I have kept it carefully stored in its box. I am selling it because I have many beer glasses. I stored it in a bag and then in the box, but the exterior shows signs of aging overall. It originally has a coating, so I don't think there is any problem with the quality. The inside is very clean, but there is one spot that looks like a stain. Please refer to photo 13. ■Size■ Diameter: Approximately 7cm Height: Approximately 9cm HICOPPER
