Not easy to break: Fast heating, resistance to oxidation and rust, and fast delivery of clean and hygienic hot water are all features of the food-grade stainless steel kettle. Easy to use: The teapot whistles automatically, to remind you when the water is boiling. Even in noisy environments, the loud whistle attracts your attention and is safe to use. More space for you: The whole family can prepare tea with this 2.5-liter kettle. As soon as the water starts to boil, a loud but gentle whistle sounds, preventing over-boiling and reducing safety risks. Ergonomic aspects: For a comfortable grip, the teapot has an ergonomically molded handle that cools down a few seconds after the cooking is turned off. A one-touch button makes it easy to turn the spout on and off, making pouring a breeze. Widely Used: The teapot can be used on ceramic, halogen, electric, induction and other stovetops. Please use a low or medium heat setting to brew tea; this will help you save energy.
