◎ Thank you for viewing. (Please also read the profile if possible) ● This is a high-quality, long-bristle "Yui 4" calligraphy brush made with fine, high-quality wool (bamboo and water buffalo horn handle / made by Koseido / 30,000 yen excluding tax at the time). It is a long-bristle brush meticulously crafted with carefully selected fine, high-quality wool, offering a good balance of softness, flexibility, and resilience, making it an excellent choice for kanji and harmonious styles of calligraphy with several lines on a strip of paper. The brush hairs have a slightly amber color, a characteristic of aged fine, high-quality wool. Due to the shortage of raw materials and technical aspects, I believe this is one of the high-quality wool brushes that is difficult to reproduce today. 【Features and Size of the Brush】 ★ High-quality long-bristle wool brush "Yui 4" <Toyohashi brush made by Koseido> (Fine, high-quality wool / long-bristle / bamboo and water buffalo horn handle / suitable for kanji, gyosho (semi-cursive script), and harmonious styles of calligraphy with several lines on half-size or full-size paper / unused for many years / 30,000 yen excluding tax at the time / Total length of the brush ⇒ approx. 29.7cm / Bristle length ⇒ approx. 6.3cm / Diameter at the base of the bristles ⇒ approx. 0.9cm) ● This is a wool brush from nearly 20 years ago, and there may be some scratches, but it is in good condition as it is an unused brush that has never been used with ink. ● Please note that there may be some differences between the images posted and the actual product due to camera functions and lighting. ● Recently, it seems that some people are illegally copying the descriptions and images from my Mercari listing page and selling them at extremely low prices on fake websites, even though they don't have the actual product.
