Founded in 1939, Duralex has been manufacturing tempered glassware and tabletop products for over 80 years in La Chapelle-Saint-Mesmin in the very heart of France. Since 1939, when Duralex invented the glass tempering process, the name Duralex has been associated with toughened glassware, utilizing their proprietary process. The tempered glasses glasses are equally suitable for cold or hot drinks, conveniently stackable, microwave, freezer and dishwasher-safe, impact and chip resistant, and the perfect weight. With the help of continuous investments and commitment to quality, Duralex has reached a level of excellence that makes its products recognized throughout the world. Duralex is and will always remain a true French manufacturer of glassware and tabletop products, and is the only glass manufacturer that makes 100% of their products in France. This new Manhattan glass is manufactured to last as long as its namesake drink and that, by all accounts, has already been since the 1800s. A Manhattan glass has to be tough to tolerate being chilled in the freezer and sterilized in a hot dishwasher. This Manhattan glass comes in three sizes (two low ball and one high ball) and features faceted lines to show off the color of the liquors. The handsome, vintage-style glasses are at home in any home bar or living room. Toughened through a tempering process to withstand the rigors of a professional bar.
