This is a set of 5 crystal glasses. The size is 4.9cm in diameter, 12cm in overall height, and 5cm in glass depth. They are likely unused. These are old items from the Showa era. My family collected alcohol glasses and they were stored on a shelf for a long time. There are no noticeable scratches or stains. The brand name is unknown as there is no original box or booklet, and there are no engravings on the glasses. ★Please refrain from purchasing if you are concerned about minor details or are looking for perfection, as these have been stored and inspected by an amateur. ※They will be shipped via courier. I work during the day, so I may not be able to respond immediately.
