Duralex is a French manufacturer of glassware, tableware and cookware. Picardie is one of the lines of of glassware they sell, and it is actually somewhat famous on their own, for good reason. I have had sets of the 3 3/4 oz. and the 12 oz. glasses for about 12 years. The good: They are made from tempered glass, like car windshields, so they are tough and resistant to breaking and chipping.
