I don't know much about these games. You can see it is made of a high quality. The Yunzi Stones are high quality as well.Please look at the pictures, I have included lot with sizes etc. The board is double sided. One edge has a slight bit of edging, please look at the pictures. The zip for the bag has come off. I don't think this has been played very much, the dust look on the black Yunzi stones is normal, if you read the paperwork which is in the pictures it explains everything.
