This series is named for its beautiful color that is reminiscent of a peaceful country lake. The unglazed border adds a rustic, handmade feeling to these Japanese teacups and creates a perfect contrast to the cool green glaze. Please note that this item has a crackle glaze as shown in an image of another item in this series. This is not a defect. Color may also vary slightly. The Kosui Green Collection. 3″ diameter x 3.25″h. 6 oz. capacity. No microwave and handwash recommended. Made in Japan.
