This is a porcelain teapot and 3 matching cups.
The pieces are gray with a cobalt blue and green Koi fish pattern.
The teapot handle is bamboo and the cups have no handles.
The cups measure 2" tall, and 2.75" in diameter, and the teapot measures 5" tall not including the handle, 7.5" wide including the spout and 5" in diameter.
These pieces are in very good pre-owned condition.
