It is especially important to thoroughly wash away the ink at the base of the bristles; if this is not done properly, ink will accumulate at the base, which can lead to the ink spoiling or the hairs breaking. After washing the brush, remove the moisture while shaping it with waste paper. It is best to store it in a well-ventilated place and dry it by hanging it.
