The Alessi 9093 kettle, which was designed by architect and designer Michael Graves and is one of the most popular Alessi objects in the world. The kettle is made of mirror polished 18/10 stainless steel with a handle and a small bird-shaped whistle in PA. Its magnetic steel bottom also works on induction hobs and when the water starts to boil, the bird sings with a whistling noise, leading to an inevitable smile.
