This set includes 96 double-headed brush-pens with a flexible nylon fiber brush tip on one end and a fine tip on the other. The brush tip works like a paintbrush to create fine, medium or bold strokes and the fine tip provides consistent lines. They contain non-toxic, fast-drying, water-based odorless ink that is blendable, allowing an endless palette of colors. The colorless blender softens and blends colors, creating a watercolor effect. Ideal for fine artists, crafters and for use with rubber stamps. This set includes all 95 colors in the Dual Brush Pen line and a colorless blender.
