This was purchased at a calligraphy supply store about 30 years ago. Speaking of inkstones, it's all about the ink! I will also give away "The Mystery of Ink: Answering Your Questions" by Bokudo. The brushes in the photo are sold separately. They are included for size reference. You can think of the smaller brush as being for half-size paper and the larger brush for long strips of paper. Inkstone size: Length: 25.5 cm Width: 15.7 cm Comes with a wooden box. Total weight: 3 kg Thank you for viewing.
