【Kurokigoishiten Official】 How to care "Clamshell & Nachiguro (slate) Go stones"

Clamshell and Nachiguro (slate) Go stones will gradually become dirty and lose their luster with use.
On our shopping site, we provide information on how to care for white and black Go stones on the "Maintenance of Go Stones" page, but it only includes cleaning methods to remove dirt.
After much trial and error to find a way to revive the lost luster of Clamshell Go stones, we have finally developed a "Clamshell (White) and Natiguro (slate) Go stones Care Kit" that allows customers to restore the luster of their stones by themselves.
Please watch the video movie to see how to clean and keep your Go stones beautiful and use them for long days to come.
