The traditional firing allows the product to be suited for boiling water and dissolving iron in moderation. The improved size and weight make it suitable for use by women. The product design has a motif of the migratory bird of the swallow bearing news of spring arrival, making for a more streamlined and refined product. The handle is part of a single continuous form, making water easier to pour and a wooden twist lid prevents burning when it is lifted. With a filter, it can be used as a teapot.
