Fineliner pens PENTEL POINTLINER S40-12, colour dye ink, 12-piece set, 0.4 mm tip

Set of 12 PENTEL POINTLINER S40-12 fineliner pens with a 0.4 mm tip and water-based dye ink, designed for precise line work, sketching, technical drawing and colouring small details. The set contains a range of vibrant colours that maintain consistent ink flow and dry quickly on most common drawing papers and sketchbooks. These fineliners are intended for illustrators, designers, students and hobbyists who need reliable, thin lines and colour variety in a compact 12-piece set.

Advantages

PENTEL POINTLINER pens feature a 0.4 mm metal-clad tip that produces uniform, accurate lines for detailed work. The water-based dye ink gives vivid, even colours and smooth flow without frequent blotting or interruptions. The pens are lightweight and easy to hold for extended use, and the 12-colour assortment covers a practical palette for sketches, diagrams and annotations. The ink’s compatibility with typical paper surfaces reduces feathering and ensures clear edges for technical and artistic tasks.

Suitable for

• Detailed sketches and illustrations
• Technical drawing, drafting and diagrams
• Colouring small areas and adding coloured accents
• Note-taking, journaling and highlighting with thin lines
• Student and hobbyist art projects requiring fine line precision

When it may not be suitable

These fineliners use water-based dye ink that may bleed or feather on very thin, highly absorbent papers or on coated surfaces not designed for markers. They are not formulated as waterproof pigment inks, so lines may run if exposed to water after application.

Key specifications

• Tip size: 0.4 mm
• Ink type: water-based dye ink
• Number of pens: 12
• Line characteristics: consistent fine lines suitable for detail work
• Suitable surfaces: standard drawing paper, sketchbooks, uncoated paper

How to use

Use the PENTEL POINTLINER S40-12 pens by holding the pen at a comfortable angle and applying light, consistent pressure to obtain thin, even lines. For best results, test the pens on a scrap of your paper type to check for bleeding or drying time. Replace caps after use to prevent the tips from drying out. Combine different colours and cross-hatching techniques for shading and texture, and layer carefully on non-absorbent papers to avoid smudging.

What to consider before purchase

• Paper type and weight — very thin or highly absorbent papers may cause bleeding
• Need for water resistance — dye ink is not inherently waterproof
• Required tip size — 0.4 mm produces fine lines; choose larger tips if thicker strokes are needed
• Quantity and colour range — set includes 12 colours suitable for varied detail work

Usage recommendations

Store pens horizontally or with caps on to maintain ink flow. For archival or water-resistant requirements, test or use a waterproof pigment pen in addition to the POINTLINER set. For consistent colour results, allow ink to dry between layers and avoid heavy saturation on thin paper.
