The kettle is made entirely of high-quality stainless steel – you don't have to worry about it breaking. The use of stainless steel makes it a purchase for many years to come. Thanks to the matching diameter of the top opening (7.8 cm), it is compatible with all Hario V60 drippers. Another advantage of the server is that it can also be used as a kettle for boiling water. You can easily heat water on a gas or electric burner in it. It is not compatible with induction and microwave stoves. Total capacity: 700 ml. Practical capacity: 500 ml.
