Although new and unused, there is some staining on the bottom of the box due to the passage of several decades. Chinese seal materials often use stones that are easy to carve, such as Shoushan stone, Qingtian stone, and Balin stone. They are also enjoyed as works of art, appreciating the carved portions. Please take a look at the item for sale, including the stone pattern (translucency in the milky white areas) and the carving. This item belongs to my older brother, who has been practicing calligraphy for over fifty years. ☆ Most of these items were purchased and stored several decades ago. He's preparing for his "end-of-life" activities (*^-^) I'm also listing other calligraphy-related items! It seems that ink and paper, etc., improve with age, but I don't understand it at all? There are many calligraphy-related items, and it takes time to research them. Please understand my lack of knowledge. I will be listing items gradually. I would also be happy if you could take a look when you have some free time. Thank you for viewing.
