Japanese Tableware ? Premium ? Japanese Cut Glass Tumblers ? Kamei Glass ? With Defects ? Set of 8

Found these at my parents' home. They were stored in a box (the box is slightly dirty), but a couple have been used. *This is a set of 8 glasses*. These are Japanese-style cut glass tumblers made by Kamei Glass. Kamei Glass is a Japanese glass wholesaler known for reviving Satsuma Kiriko. These Japanese-style cut glass tumblers have a retro feel. They are a convenient size for everyday use, suitable for highballs, cold tea, beer, etc. As shown in the last photo, they are currently sold as sets on Amazon and other sites, and are a popular design for gifts or for entertaining guests. There don't seem to be any major damages to mention, but please understand that these are used items and have been stored at home. The diameter of the opening is about 6cm, and the height is about 11cm.
