Good design is achieved when functionality dictates form. The double-walled glasses of the BISTRO line are primarily designed to keep cold drinks cold and hot drinks hot. Although their design is kept in simple round shapes and intended for everyday use, the glasses are something special. The BISTRO glasses are made of extremely heat-resistant mouth-blown borosilicate glass, which provides excellent insulating properties. The BISTRO glasses are suitable for chilled drinks and all kinds of coffees.
