Thank you for viewing! [Product] Go stones, extra large, clam-shell go stones, Nachiguro, approximately 11mm thick. Go bowls, kaya wood, extra large, size 40 Go stones Clam-shell: 178 pieces Nachiguro: 177 pieces *The number of pieces may be incorrect. Please check the photos. [Condition] When measuring the thickness, both the clam-shell and Nachiguro stones were over 11mm (this is just a rough measurement). I did not find any chips or damage on the go stones themselves. (Please understand that there may be oversight.) One of the cases has a chip. It is a clean chip, so it should be usable if glued back together. Please check the photos for details.
