This is part of a collection my father acquired by visiting Mr. Otani's solo exhibitions around 30-40 years ago. Most of them have only been displayed and never used, but we are carefully inspecting them for any scratches or damage. Diameter: Approximately 12.5 cm, Height: 5.6 cm This is a set of two medium-sized bowls with bubbles. It's a set of two, one in Otani Blue green and one in a bright green. ■ We have many other items from the collection for sale, so if you are interested in multiple items, we will create a dedicated page for you. ■ We will pack them carefully, so it may take a little time to ship. Thank you for your consideration.
