How to use

Hold the pen at a comfortable angle and apply light pressure for thin lines and increased pressure for broader strokes. Use steady, continuous motions when forming strokes for lettering, or short expressive strokes for sketching and texture. Test strokes on scrap paper to gauge pressure and ink flow before working on a final piece. Cap the pen after use to protect the brush tip and prevent drying.

Usage recommendations

For best results, use smooth paper designed for markers or mixed-media pads to reduce bleed-through and feathering. When combining with other media, allow the fluorescent ink to dry fully before layering water-based washes or applying solvent-based media.
