Thank you for viewing. This is a Noritake Portshore mug made of bone china. Size: Mouth diameter: approximately 7.8cm Bottom diameter: approximately 6cm Height: approximately 9.5cm It has never been used and has been stored at home. The box is a little dirty. Although I have inspected it, there may be small imperfections such as stains or dirt that I may have missed. Please consider purchasing only if you understand this. As it has been stored at home, there may be some storage odors. If you are sensitive to smells or are looking for a perfect product, please refrain from purchasing. If you have any concerns, please refrain from purchasing. I will pack it as compactly as possible when shipping. Thank you for your understanding.
