HARIO Teapot with a round design that makes it easy for the tea leaves to move up and down in the teapot when you put the tea leaves in the teapot and pour freshly boiled hot water. The spout has a 24-karat gold-plated tea strainer, so the tea leaves open well in the teapot. Because it is made of heat-resistant glass, you can see the inside of the teapot clearly, and you can enjoy the color of the tea and the appearance of the tea leaves opening and jumping. *If you remove the tea strainer, you can also use the microwave oven.
