Nachi Black Ink Stone This is something I was given when I was 10 years old. There is a scratch = carved on the back. Mount Nachi S51.6.27 This is the date of purchase. I remember using it once... It has been stored for a long time. Please purchase with your understanding. If you wish, I will include a sample sheet (with your desired characters on a piece of hanshi paper). Currently in my 32nd year of teaching, this may be the origin of my calligraphy teaching, with students ranging from 5 to 91 years old (*^*)
