The box shows signs of aging. Top-quality cigarettes, Shanghai We are looking for someone who understands this item. This is from my brother, who has been doing calligraphy for over fifty years. Most of these items were purchased and stored decades ago. It seems that both inkstones, paper, and ink improve with age, but I don't understand any of it? I'm listing these items at his request! There are too many to research, so it's taking time. I will be listing them little by little. I would be happy if you could take a look when you have time. Thank you for looking.
