This is from my older brother, who has been practicing calligraphy for over 50 years. Most of these items were purchased and stored several decades ago. It seems that both the ink and paper are better with age, but I'm completely clueless? There are too many items, and it takes time to research them. I will be listing them little by little. I'm also selling inkstones, old ink, seal engraving stones, etc.! I would be happy if you could take a look when you have some free time. The outside of the box is slightly dirty. There are large and small Huangshan pine soot inks, so please check the size. Thank you for looking.
