How to use

Remove the cap and hold the pen at a natural writing angle. Apply light to moderate pressure for consistent line width; heavier pressure may produce broader strokes. For optimal results on paper, write or draw in steady motions to avoid interruptions in ink flow. Replace the cap after use to prevent the tip from drying out. If using on non-porous surfaces, test on a small area first to confirm adhesion and drying time.

Recommendations

Store horizontally or capped at room temperature and avoid direct sunlight or freezing conditions to preserve ink consistency. Use suitable paper grades for best color saturation and minimal bleed-through; for archival or water-resistant needs, verify compatibility of the ink with sealing or fixative products before application.
