The Bialetti Musa Restyling polished stainless steel espresso maker comes from the award-winning design team of Guido Bergna. The fashionable stainless steel design focuses on stylish elegance. It is suitable for use on most hobs including gas, electric and pyroceramic hobs. It is not suitable for induction hobs. The Musa also features a new elegantly shaped knob which makes it easier to open the lid. Please note that the cup size is based on espresso cup sizes and not on regular tea or coffee cup sizes.
