Bodum has blended practicality, efficiency and durabililty, with good design in this kettle. You can see the water as it boils, always handy when you're in a hurry, but without the problems found in other glass kettles. The clear water container is double-walled, keeping the water hotter, longer, and keeping the outside cooler to the touch.. Not only that, the inner wall lis borosilicate, laboratory glass, and the outer wall is clear plastic. So, only glass comes in contact with your water, but that glass is protected from breakage. 1-1 liter capacity, auto-shut-off for safety.
