Color Twin Brush comes out dual-sided in order to provide more drawing options and flexibility in strokes. Brush tip works like a paintbrush to create bolder strokes. On the other hand, fine tip brush is there for more soft touches on artwork. The brush mark on the side of the brush lets you know the type of brush you are using. It is also possible to create blending effects by using a water brush or rubbing two brushes together. Perfect for use by artists, craftsman, illustrators, students and more.
