Songkeng Huiwen Inkstone Width 13.7cm x Length 20.2cm With Box This is a Suiko inkstone purchased about 10 years ago from a long-established calligraphy supply store in Katsushika Ward. It was explained that this inkstone was made from stone collected from the Songkeng quarry. The purchase price was 25,000 yen (excluding tax). Because of its large size, I used it when writing large-scale works. I think it's a practical inkstone. I have too many inkstones, so I've decided to organize them. Thank you.
