This is a glass teapot (kyusu). It's for hot water and cannot be placed directly on a flame. It has a cute, rounded shape. It's also great for black tea and Chinese tea. The transparent glass allows you to see the color of the tea and the tea leaves unfurling, which is a nice touch. 〈Dimensions〉Approx. 15cm (at the center of the pot) Height: Approx. 14cm (to the top of the lid knob) It's new and unused, but it has been stored outside of its box.
