This is a glass for cold sake, specifically designed for use with an ochoko (small sake cup). I'm offering it because I thought it would be enjoyable to toast with chilled sake on a summer night. This is a non-commercial item. The size is approximately 55mm in diameter and 65mm in height. Please refer to the photos for your assessment. Although unused, it is a rather old item. I ask for your purchase with understanding. Thank you for looking.
