This is a simple rock glass made of crystal glass. The clear, wide-mouthed rock glass can be used not only for whiskey and shochu, but also for cold tea, iced coffee, and other beverages for those who don't drink alcohol. I am selling this to declutter. It is a new, unused item. It has been stored at home for a long time. Please refrain from purchasing if you are sensitive to this, as it has been stored by a private individual. T769-1564 Iittala Baccarat
