Menryo Tansen is a type of Xuan paper (senshi), a type of calligraphy paper. I have 100 sheets in stock from my mother, who was a calligraphy teacher, but they have some stains because they were opened. Some sheets without stains are also mixed in. Although there are stains, the paper is not burnt and is clean. Please purchase only if you understand this. Thank you for looking. 15
