Riedel Vinum Crystal Martini Glasses - Set of 4 Premium Cocktail Glasses for Martinis, Margaritas & Cosmopolitans - Perfect for Home Bars, Parties & Elegant Entertaining

I have used these for a few years. I’m pleasantly surprised how well they stand up to heavy use. I keep one in the freezer and have a daily martini. I have not had any breakage with the freeze to room temperature changes and daily use. They are of great quality and hold 5oz. Perfect size for a standard Gin Martini. So I needed more for parties
