How to use

Hold the pen at a comfortable angle and apply light to moderate pressure for smooth, even lines. Use the 1 mm tip for clear, visible strokes when marking text or filling forms.

Usage recommendations

For optimal results on thin paper, test the pen on a small area to check for bleed-through. Use steady, moderate pressure to maintain an even ink flow and avoid excessive force that may cause blotting or premature wear of the tip.
