Brush Pens & Markers
Brush pens are great for coloring and for creating brush letter calligraphy. The brush tips allow for painterly style artwork without the hassle of paints and brushes, and many brush pens are blendable, so you can create watercolor-style works conveniently. Some of the most popular brush pens include the Tombow Dual Brush Pens, Pentel's Pocket Brush Pen, and Kuretake Clean Brush Pens.
