Fineliner pen PENTEL PointLiner Colour S40 0.4 mm, black ink

The PENTEL PointLiner Colour S40 0.4 mm fineliner pen delivers a consistent, precise black line intended for detailed drawing, technical sketching and clear handwriting. Its 0.4 mm metal-clad tip provides controlled ink flow for fine contours, lettering and annotations on paper-based media. The pen is lightweight with an ergonomic barrel that supports extended writing and sketching sessions while maintaining line accuracy and minimal bleed on standard paper types.

Advantages

This fineliner offers a firm 0.4 mm tip that preserves point definition over repeated use and produces uniform black ink lines suitable for illustrations and technical notes. The water-based ink dries relatively quickly, reduces smudging, and is compatible with a range of paper weights. The slim barrel and balanced weight make the pen comfortable for longer tasks while enabling precise control for detailed work.

Suitable for

• Technical drawing and drafting where narrow, stable lines are required
• Illustration, ink sketching and line art
• Hand lettering, annotations and note-taking
• Journaling and planners that require fine, consistent writing

When it may not be suitable

This pen is not intended for use on glossy, coated or non-porous surfaces where water-based ink may not adhere properly or may take longer to dry. For work that requires very broad strokes, high ink saturation, or marker-level coverage, a broader-tipped marker or pigment-based pen would be more appropriate. Heavy pressure or use on very rough surfaces may accelerate tip wear.

Key specifications

• Tip size: 0.4 mm metal-clad fineliner tip
• Ink type: water-based black ink
• Line characteristic: fine, consistent black lines with low bleed on standard paper
• Barrel: slim, ergonomic design for comfortable grip
• Intended media: paper-based surfaces such as sketchbooks, notebooks and technical paper

How to use

Hold the pen at a comfortable angle and use light to moderate pressure for the finest, most consistent lines. For technical work, use a ruler or templates to guide straight lines; for illustration, vary angle and pressure slightly to adjust line weight. Allow the ink a few seconds to dry on thinner or more absorbent papers to avoid smudging. Store capped when not in use to prevent tip drying.

What to consider before purchase

• Confirm that a 0.4 mm fine tip is suitable for your intended level of detail
• Consider paper type—very smooth or glossy papers may not perform optimally with water-based ink
• Evaluate whether water-based ink and black colour meet archival or permanence needs

Usage recommendations

Use this PENTEL PointLiner Colour S40 0.4 mm fineliner on standard sketchbooks, notebooks and technical pads for precise lines; combine with pencils for underdrawing and with light washes after ink has fully dried.
