Durable 18/10 stainless steel is used for the kettleâ€™s body, and the handle and bird whistle are crafted in PA. Inspired by Alessiâ€™s desire to represent the exciting combination of top-notch design with innovative methods of mass production, the kettle design was created by Michael Graves. Blending his personal visual precision with a wide range of influences, including Art Deco, Pop Art, and even the spirit of cartoons, Graves fashioned a functional visual masterpiece with this kettle. Among tea makers and infusers, this kettle stands out. Use it daily to brew delicious, healthy teas that can boost your immune system and help improve overall health.
