Yellow overlay cut glass crystal glass sake cup. I believe this is Satsuma Kiriko, but I cannot definitively confirm the workshop as there is no original box or other identifying information. Please make your own judgment based on the photos. This item was previously given to me by a relative, but there are no engravings or signatures on the bottom of the glass. It has a substantial feel and is made of crystal glass, so it produces a beautiful sound when flicked with a finger. As there is no original box, I have listed it at a low price. ✿Product Size✿ Diameter: Approximately 60mm Height: Approximately 85mm ✿Product Contents✿ Sake cup: 1 No accessories included. Will be carefully packaged in a gift box. ✿Product Condition✿ Unused, stored item. There are no noticeable scratches, and it is in a very clean and lustrous condition. Please be aware of any minor, unnoticed scratches. Please be aware of any impurities, scratches, bubbles, or indentations that may occur during the manufacturing process. The product is a used item that has been in someone's possession once. Please understand this before purchasing. I am also listing other items such as Kiriko, Edo Kiriko, Satsuma Kiriko, and Kagami Crystal, so I would be grateful if you would take a look.
