I enjoyed using this, but it's heavy and I haven't been using it much physically, so I'm selling it. The quality of the wood is unknown, but I believe it's high quality. I'll include genuine clamshell stones and Nachi black stones. If you'd like an old wooden go-ke (stone container), I can replace it. The lid of the hinoki go board was unfortunately broken recently, so it won't be included, but I will use it as a protective board during shipping. Price reduced further! Please consider. The material of the stones is Nachi black and clamshell.
