Thank you for viewing. [Rough Kofuh Kenko Brush, Upper Wisdom] I can't read the characters written directly on the brush. Please confirm. Purchased for 30,000 yen. The base of the brush is hardened with ink (photo 4). My mother, who is a calligrapher and runs a calligraphy class, purchased this for large format works and stored it at home. The cap is deteriorated. What is Rough Kofuh? It is made from the hair of goats (mountain sheep) that live in the Jiangnan region of China. To distinguish it from ordinary goats, it is also called "sanyomo" (goat hair). Each part of the body's hair has different characteristics and is used as a material for brushes. In particular, the hair between the front legs (chest) and from the neck to the throat is called "Fine Kofuh" and "Rough Kofuh," and the longer the transparent part of the tip, the better the quality of the hair. What is Ten'o? It is the hair near the base of a horse's tail, and it is characterized by its strong waist and elasticity. What is a Kenko Brush? It is a brush made by combining hard and soft hairs. It has characteristics between a Gougou brush (hard hair brush) and a Jūmō brush (soft hair brush), making it easy to use for beginners to advanced users. By mixing hairs from different animals (or hairs of different hardness from the same animal), it achieves both moderate elasticity and good ink absorption, and can be used for various calligraphy styles from Kaisho (block script) to Sosho (cursive script).
