The thickness and diameter of our Go stones are slightly different between white Go stones and black Go stones of the same size. The thickness of Nachikuro Black Go stones is 0.3mm thicker and the diameter is 0.3mm larger than Clamshell White Go stones of the same size.
The reason for this is that white is an expansion color, so when white and black stones of the same diameter and thickness are viewed by the human eye, the black stones appear slightly smaller, so they are adjusted to appear about the same size. If the black stones look smaller on the board, it would seem psychologically disadvantageous, so the stones are adjusted so that they appear to be about the same size to the human eye.
Each clam shell stone produced in our workshop carries specific numbers on its surface.
This numbering system will help us track our products and clarify our liability.
We will continue to make every effort to further improve the quality of our products and our quality assurance system.
*The numbers become visible when the stones are exposed to black (ultraviolet) light.
This new numbering system will help us further improve our quality control and assurance system.
Up until now, manufacturers had no unified sorting standards, which makes it hard for customers to distinguish genuine brand stones from inferior/second-hand ones.
Many customers find it extremely hard to know the true value of clam shell stones. We believe that our newly-introduced numbering system will help customers around the world understand our strong commitment to our products and liability.
