It allows creating wash drawings or very fine and precise lines. The small gray bristles are the smallest you can find in a paintbrush. The tuff of bristles gather together in a tip like magic. Care: Caring for paintbrushes is essential to keeping them in good working condition and to their life span. Watercolors: dip the paintbrush in water and rinse in warm water. Oil: dip the paintbrush in a solvent such as taltine. Clean in soapy water and rinse in warm water. Acrylic: clean in soapy water and rinse in warm water. Practical information: Never let dry before cleaning.  Using a hydrating paintbrush cleaner after using taltine or soap prevents bristles from drying and keeps the supple shape of the paintbrush.
