Yasutomo SW Series Bamboo brushes are of good quality. A soft, absorbent hair surrounds a stiffer core. The core determines the length and provides linear stability, the outer hairs are soft for the retention of water, and snap to a fine point. The hybrid of horse, badger, deer, and sheep hair found in this brush make the performance dynamic and unlike other natural hair brushes. This is a good quality, professional grade brush at a good value.
