Tombow Dual-Brush Pens have the benefit of a flexible, brush tip on one end, and a fine point on the other. The nylon brush end can create thin to thick lines based on the pressure of the stroke. The fine tip delivers smooth, consistent lines. Waterbased Ink is nontoxic, acid-free, odorless, non-bleeding, and blends easily. Ideal for drawing, stamping, lettering, and journaling. 10 Pastel Colors include Carnation, Pink, Light Ochre, Pale Yellow, Mint, Sky Blue, Process Blue, Lilac, and a Colorless Blender.
