These go bowls are Kokutan (Ebony), a very dense wood in the Rosewood family. They feature lovely black and red patterns and are size L. When purchased new, bowls of this type typically cost $500-$700.
There are 180 go stones of each color. The white are Japanese clams that measure 7.5mm-7.8mm. I believe they are Suwabute, or Legendary grade. They have an amazing patina from age, so I have washed them but refrained from soaking them in h2o2. If you would like, I can clean them per our Care Instructions, but I will leave that decision to you and the service will be included in the purchase price. The black stones measure 7.5-8.0mm and are high-grade Japanese glass.
