Antique Shogi board

I'm not sure exactly when it's from...My mother told me she received it from her uncle, who used to run an antique shop a long time ago.Since my mother is elderly, it's quite old.It has a heavy feel to it, and while it has some scratches and dirt, it has a stunning black luster and a commanding presence.I brought it home when we cleared out my parents' house, but I don't need it, so I'm offering it to someone else.It's stylish just to have it on display.There's a faint, round stain on the surface. Please check the photos.I hope someone will appreciate it.Thank you. Perfect for everyday use. excellent materials and excellent craftsmanship ensure long-lasting durability.
