For watercolor painting on watercolor paper, Graphix Aqua dual-tip pens offer high-quality, lightfast, waterbased pigment ink in a range of brilliant colors. Use the contour tip or the flexible brush top to apply color, then use a wet brush to spread it - do not dip the Graphix Aqua pens into water.
