With the new Bialetti Rainbow range of stove top espresso makers, the original stove top Moka Express coffee maker, made by Bialetti in Italy, has further evolved. The aesthetical transformation is noted in the smoother lines of the black acrylic handle and knob with more visibility given to the Little Man with the Moustache. The functional evolution improves the ergonomics and guarantees top quality and complete safety. The Rainbow Espresso Maker is made from solid cast aluminium with a yellow soft touch scratch resistant coating. All pressure valves are fitted with top quality stainless steel springs and ball bearings for safety and durability.
