These go bowls are Ebony, a very dense wood in the Rosewood family. They feature lovely black and red patterns and are size L.
There are 180 go stones of each color. The white are Japanese clams that measure 7.6mm-7.8mm. I believe they are Suwabute, or Legendary grade. They have an amazing patina from age, so I have refrained from washing or soaking them. 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 8-8.2mm, and it is common for the black to be slightly thicker than the white stones to counteract an optical illusion - if they are made the same size the white will appear larger.
