These glasses are made of tempered glass, making them shock- and chip-resistant, ideal for hot and cold beverages, and safe for use in the dishwasher, the microwave, and even the freezer. They're stackable for easy storage. Made in France.
After inventing the glass-tempering process in 1939, Duralex has spent the decades since making stylish, functional, and durable tempered glassware and tabletop pieces in La Chapelle-Saint-Mesmin, France. Much like its process, the quality of its glassware has remained unchanged over the years, and these traditions have helped the company become a familiar name in households around the world.
