5 Pitt Artist Pen Dual Markers (orange glaze 113, middle purple pink 125, purple violet 136, phthalo blue 110 and leaf green 112). Package with hang tag for easy display. Pitt Artist Pen Dual Markers feature a smooth, flexible brush nib that retains its shape for artistic work and a metal-encased 0.8mm fiber-tip for adding detail. The thick brush nib is suitable for fine to thick lines and allows for vast coverage, while the fiber-tip is ideal for fine drawing, contours, lettering and accents. The finest India ink in a practical drawing pen: the water-based ink is highly pigmented with excellent lightfastness. It is pH neutral, acid-free, odorless, permanent, smudge and waterproof when dry and will not bleed through most paper. Overlapping colors in layers results in interesting mixed tones and emphasizes the varying depths of a picture. The markers have a large ink reservoir and roll-away locks on both caps.
