White Hair Brush : Goat hair (very soft, good absorbing capacity)

Mixed Hair Brushes : These calligraphy brushes are made from different types of hair, and combine brown and white hairs. The stiff brown hairs from the inner core of the brush are used for their resilient quality, while the outer white hairs ensure the suppleness of the brush tip.
