Poster – Needed to Write a Passionate Letter?

The ink used in today's pens must dry quickly, leaving the paper dry and smudge free. The ink of fine liners is water-based to ensure easy writing and environmental friendliness. The fibre-tip nib is made of nylon and is often clad in metal to ensure more stability and optimal script with a line width of 0.3 or 0.4 mm. A fine liner pen may be left uncapped for a few days without the ink drying out.
