The enamel on steel Zen Kettle features a modern rounded design that feels at home in both classic and contemporary kitchens. It's crafted from fast-heating premium carbon steel and finished with a colorful enamel in our stylish palette of colors. In addition to tea, the Zen Kettle is useful for preparing French press coffee, oatmeal and more. Durable carbon steel heats water rapidly, and a fixed single-tone whistle alerts when the water has reached a rolling boil. Chip-resistant, non-reactive, resistant to stains, and easy to clean.
