Thank you for looking. (Please read my profile as well if possible.) This is a high-quality long-bristle calligraphy brush made of sheep wool, named "Gokuhin Kosho" (bamboo and water buffalo horn handle / 60,000 yen at the time). It is a superior quality long-bristle brush meticulously crafted from carefully selected fine and lustrous bristles, with a good balance of softness, flexibility, and resilience, making it suitable for large-format kanji in gyosho (semi-cursive script) and other styles. Due to the shortage of raw materials and technical challenges, it is a top-tier sheep wool brush that is difficult to reproduce today.
