Key specifications

• Tip size: 0.3 mm fine point
• Ink color: cool grey
• Writing system: water-based fineliner ink
• Line consistency: narrow, precise lines suitable for detail work
• Barrel: slim, lightweight design for ergonomic handling

How to use

Hold the fineliner at a comfortable angle and apply light, even pressure for a consistent 0.3 mm line. Use short, steady strokes for detailed areas and longer, continuous strokes for outlining. Allow a few seconds for the ink to dry on the paper to avoid smudging when layering or erasing nearby pencil marks. Store capped when not in use to prevent the tip from drying out.

Usage recommendations

Use the SMARTMAX cool grey fineliner on standard drawing or writing paper for best results. For technical work, pair with quality rulers and templates to maintain precise lines. If combining with water-based markers or washes, test ink compatibility on a scrap sheet before applying to final work.
