Fineliner pen PENTEL Pointliner Colour S40 0.4 mm – colored ink cartridge

PENTEL Pointliner Colour S40 0.4 mm is a precision fineliner designed for detailed drawing, technical work and neat handwriting. The pen features a metal-clad 0.4 mm tip and a colored, water-based archival-quality ink that delivers consistent flow and stable line width. The slim barrel and balanced weight support controlled strokes for sketching, note-taking and color accents in illustrations.

Advantages

The metal-clad 0.4 mm tip provides durable edge stability and accurate line control for fine details. Water-based archival-quality ink resists rapid fading and offers smooth, even flow without excessive bleeding on most papers. The colored ink option allows clear contrast for diagrams, annotations and artistic accents while maintaining consistent line width across different drawing speeds.

Suitable for

• Technical drawings and drafting where precise 0.4 mm lines are required
• Sketching and illustration that need consistent fine lines and colored accents
• Note-taking, annotations and journaling for clear, legible text
• Color-coding and diagramming in office, study or studio work

When it may not be suitable

The 0.4 mm tip is optimized for fine lines and detailed work rather than broad coverage; it will be slower for filling large areas compared with broader-tipped markers or brushes. On heavily textured or very absorbent papers the water-based ink may feather slightly or require testing to ensure the desired result.

Key specifications

• Tip size: 0.4 mm metal-clad fineliner tip
• Ink type: water-based archival-quality colored ink
• Line characteristic: consistent fine line suitable for detailed work
• Barrel: slim, lightweight design for controlled handling

How to use

Hold the fineliner at a comfortable angle and apply light, even pressure to maintain a uniform 0.4 mm line. For technical drawings, use a ruler or template to guide straight strokes; for sketching, vary hand speed rather than pressure to adjust line darkness. Store capped when not in use to prevent the tip from drying out. If switching between paper types, first test on a scrap to confirm bleeding and drying time.

What to consider before purchase

• Preferred line width — 0.4 mm is intended for fine detail rather than filling large areas
• Paper type — test on your paper to check for bleeding, feathering and drying time
• Color choice — colored ink is suitable for contrast and annotations but verify color tone visually if color-critical

Usage recommendations

For consistent results, use the PENTEL Pointliner Colour S40 0.4 mm on smooth, medium-weight papers and keep the cap on when idle. Combine with broader markers or brushes for mixed-media work, and use light, steady hand movements to preserve tip life and line uniformity.
