Daler-Rowney Aquafine Brush - One Stroke 1 inch (25mm) (DRABOS25) Aquafine uses Daler-Rowney's unique formulation of thick and thin filaments, tapered to a point, as well as different lengths to become a remarkable imitation of natural sable hair. This special construction allows Daler-Rowney synthetic brushes to outperform all other synthetic brushes in point and stroke, and guarantees that the brushes will not split. They have excellent shape retention and longer life than natural sable hair. The long hair is excellent for long single strokes. Good colour-holding for washes, glazing and design, thick and thin strokes.
