The Inventum CBW010 features a sturdy, stainless steel casing and a large 1.7-liter capacity. The volume marking lets you measure the desired amount of water you'd like to boil, directly in the kettle. You can easily fill the kettle under the tap thanks to its large opening. While you're pouring the water into cups, the limescale filter holds back any limescale particles. The filter is removable, so you can easily rinse it under the faucet.
