Done in a traditional Japanese style, the Xilin cast iron teapot will keep your tea nice and hot for hours. This is thanks to the cast iron construction and enamelled interior, which retains heat far better than other materials. The exterior is a stunner: Bumps along the outside are evocative of the roof of a Japanese temple. There’s also a curved spout for precise pours and a carry handle to bring the teapot to the table. Available in two colors, the pot comes with a stainless steel tea filter.
