The bird-shaped whistle at its tip sings when the water boils—a happy surprise from a classic design. Its film credits are a fitting honor: Graves worked tirelessly to develop a product that would symbolize the meeting of great design and mass production, while imbuing it with Art Deco and Pop Art influences. Capacity: 3.75 oz. Magnetic stainless steel heat-diffusing bottom. 18/10 stainless steel. Mirror polished. For best results, clean routinely using warm water, wiping in the direction of the polish lines, and dry using a microfiber cloth.
