Graphik Line Maker Graphite 0.5-0.5mm

These pens are similar to a graphic pencil in that it creates smooth free-flowing lines, yet they feature permanent pigmented ink. The ink is water-based and solvent-free. The Japanese nib is lightfast and archival, and the barrel is clear for easy ink visibility. Both the marker tip and cap indicate the ink color. They are AP and ASTM certified.
