This is a New Bone china mug from Luzerne, a Singaporean ceramic manufacturer. New Bone china uses a large amount of kaolin, a natural clay mineral, and is fired at high temperatures, resulting in a hard surface that is resistant to scratches from cutlery. It is used in five-star hotels and restaurants. In Japan, it is available at the Narumi official online shop. I brought it back from my parents' house as it was unused, but I'm selling it because I don't use it. There is no box, and it has been stored in a cupboard. There are no chips or cracks. It is in beautiful condition with no noticeable scratches. Please understand that it has been stored by a private individual. - Size: Approximately 12cm in height, approximately 8cm in diameter Thank you for looking.
