The Boston teapot is made of high-quality metal and features a double insulation wall. This keeps the tea hot and flavorful for up to an hour (when the teapot is filled to at least 90%). The specially designed spout ensures that the teapot pours optimally and without dripping. Thanks to the high-quality metal, the teapot will last for years. The teapot has a capacity of 1.1 liters, which is equivalent to 5 cups of tea.
