Duralex Classic Glass Picardi 220cc Type. Commonly used in restaurants and cafes. The wide mouth allows you to use it not only for drinks but also for dessert cups. Set of 6 DURALEX is an all-over tempered glass product that is resistant to impact and can withstand sudden changes in temperature. For example, pour hot water directly into a glass or microwave frozen food in a glass vessel to make it difficult to use with ordinary glassware. Even in the event of breakage, it will break into a small block and become less likely to become a sharp cross section than ordinary glass, but the risk of injury may be shattered. Please handle with care.
