◆ Features This calligraphy brush for elementary school students is the perfect size for writing on "Yatsugiri-ban" paper (approximately 380mm x 270mm). Made with white hair, it's soft and suitable for semi-cursive script used by upper elementary and junior high school students. ◆ Size Diameter Ф15 x Bristle Length 58 ◆ Brush Care Instructions after use: After use, wash the ink off the bristles with water, gently massaging it with your hands. It's especially important to thoroughly wash away the ink at the base of the bristles. If this isn't done properly, ink can accumulate at the base, leading to ink decay and broken hairs. After washing, shape the brush and remove excess water with waste paper. Store in a well-ventilated place, hanging to dry. Thank you for viewing.
