The Hario Teapot Kyusu 450ml is also known as the Chacha Kyusu Maru teapot and is designed for both modern style and exceptional functionality. As functional as it is beautiful and, as with all Hario products, the teapot is made of fine heat-resistant glass. The built-in stainless steel filter effectively keeps the tea leaves inside, but is easily removed for disposal and cleaning. The Hario Teapot Kyusu 450ml is the perfect balance between elegance and functionality, giving tea lovers a pot to be proud of.
