When form follows function, design just works. Abiding by this belief, the Bistro double wall glass line serves best if used to keep ice cold drinks cold and hot drinks hot. It is shaped without too many edges and corners, employing a form for everyday use, but with the special double wall glass effect. The Bistro line is made of mouth-blown borosilicate glass known for its amazing insulating qualities. The glasses come in 7 different sizes, 4 with a handle and 3 without. It is a perfect glass line for people enjoying a whole range of beverages: from ice cold drinks to espresso or latte.
