This is a Dansk Spectra cocktail glass, a gift. It's said that the color of the glass at the bottom will reflect beautifully when you pour in a drink. The thick base provides good stability. It's not made of tempered glass, so the instructions say not to use a dishwasher. The capacity is 200ml, according to online research. The glass has become cloudy from being stored for a long time, but I'll leave it as is since washing it might classify it as used. Thank you for your understanding.
