■ Go Stones Set White: 183 stones Black: 179 stones I'm not very familiar with this, but from what I can see, there is no discoloration or chipping, and they appear to be in beautiful condition. There is no stickiness either. By the way, the black stones are a little over 9mm thick. The white stones are slightly thinner. (Please understand that these measurements are approximate.) The white stones appear to be made of a natural material, and due to their nature, some have a slightly patterned color. The material of the black stones and the go stone case is unknown. This set was stored for many years by a family member. I will sell it to someone who can use it. Please purchase if you understand that this is a home-kept item.
