This set came to Baduk Club from an antique shop in Tokyo.
There are 182 black and 180 white pieces. The black are slate, about 9mm. The white are clamshell, about 8.8mm. They look like Japanese clamshell, based on the density of the lines, but could also be snow-grade Mexican clamshell. They have a slightly creamy patina from age. The black clearly fill the bowls more completely than the white, and this is common, as the black stones are just slightly wider - if they are made the same size then the shiny white stones appear larger when the pieces are side by side.
The Japanese go bowls look like Ash, with a patina from age. Also called Shiochi, they have a nice brown color that has become darker with age. They look like XL size based on how they fit the stones.
This set is still in Japan, it has not been cleaned in our Colorado shop. This is why we can offer it at a discounted rate. It may be possible to brighten the clamshell stones, to restore the wooden bowls, and to buff the slate stones with mineral oil, but we leave that to you.
Please refer to the photos, as we do not have additional information.
