Shima-Kuwa (Premium Island Mulberry)

Made from Shima-Kuwa (Premium Island Mulberry), a scarce type of wood produced in Mikura-Jima, a volcanic island in Japan.
The highest quality Go bowls are made of Shimakuwa, a highly popular type of wood with the characteristics of it shining gold under proper lighting but difficult to be found. As a natural breathing material, its texture and color turn finer and deeper over time.
