Fine-liner pen PENTEL PointLiner Colour S40 0.4 mm — red ink

PENTEL PointLiner Colour S40 0.4 mm is a fine-liner pen with red ink engineered for precise drawing, sketching, technical illustration and clear note-taking. The 0.4 mm fibre tip delivers consistent, even lines and a reliable ink flow tailored for paper-based work in art, design, architecture and everyday office tasks. The pen body offers comfortable handling for steady line control and the ink dries quickly to reduce smudging on most papers.

Advantages

The fine 0.4 mm tip enables accurate line work and detail without frequent pressure changes; the ink formulation provides uniform colour and smooth flow across a variety of paper types. The compact design and capped closure help protect the tip and prevent accidental drying during storage. Red ink offers a clear contrast for corrections, annotations and emphasis in sketches or documents.

Suitable for

• Technical drawing and architectural sketches
• Illustration and fine-detail sketching
• Note-taking, editing and document markup
• Outlining and adding coloured accents in art and design projects

When it may not be suitable

This fine-liner is intended for paper surfaces and may not perform well on non-porous materials such as plastic, metal or glossy film. The 0.4 mm tip is optimized for detailed work rather than broad coverage, so it is not the best choice when wide strokes or rapid filling of large areas are required.

Key specifications

• Tip size: 0.4 mm
• Ink colour: red
• Tip type: fibre/felt fine-liner
• Line quality: consistent, even lines suitable for technical detail
• Drying: quick-drying ink for reduced smudging on paper
• Body: lightweight pen barrel with capped closure for tip protection

How to use

Remove the cap and hold the pen at a comfortable angle to the paper to produce smooth, controlled lines. Apply light, steady pressure for the finest results and slightly firmer pressure for marginally darker or thicker lines. When transitioning between detailed work and broader strokes, maintain consistent hand movement to preserve line evenness. Replace the cap after use to protect the tip and minimise drying.

What to consider before purchase

• Intended surface: best performance on paper and stationery-grade substrates
• Desired line width: 0.4 mm is suited for fine detail rather than broad coverage
• Ink colour needs: red for highlighting, corrections and coloured accents
• Frequency of use: capped storage is recommended to prolong tip life and prevent drying

Usage recommendations

For consistent results, test the pen on a scrap of the same paper before final work, and store horizontally or capped when not in use. Use the red PointLiner for annotations, emphasis and precise outlines in drawings or documents where clear contrast is required.
