Fineliner pens PENTEL YS20P-8 set — permanent black ink, 8-piece (various tip sizes)

PENTEL YS20P-8 is an 8-piece set of permanent fineliner pens with black pigment ink certified to ISO 14145-2. The pack contains one pen of each tip size from 0.03 mm to 0.8 mm, enabling a continuous range from ultra-fine detail to bold lines. Pens are designed for drawing, technical sketching and writing where water- and fade-resistant archival-quality lines are required. The set is presented in a compact cardboard wallet for easy storage and transport.

Advantages

The PENTEL fineliners deliver consistent, water- and fade-resistant black lines thanks to ISO 14145-2 certified pigment ink. Multiple tip sizes in a single set cover very fine detailing up to thicker outlines, while a robust tip construction helps retain shape during regular use. The permanent ink is suitable for mixed-media workflows and provides strong contrast on most papers.

Suitable for

• Illustration and ink drawing
• Technical drawing, architectural and engineering sketches
• Note-taking, journaling and precise handwriting
• Outlining and detailing in mixed-media art (with watercolours or dye inks)
• Students, designers and office use requiring archival lines

When it may not be suitable

These fineliners use permanent black pigment ink, which is water- and fade-resistant; however, they are not intended for use where erasability is required. The fixed tip sizes mean line width cannot be adjusted continuously beyond the supplied range. On heavily textured or very absorbent papers, ink appearance and line crispness may vary.

How to use

Select the tip size appropriate for the task — use finer tips for detailed linework and thicker tips for outlines and shading. Shake the pen gently if recommended by manufacturer instructions, then place the nib at the intended start point and draw with steady pressure; the rigid tip supports controlled strokes. Allow ink to dry fully before layering with watercolour or applying additional media to prevent smudging under wet conditions. Replace caps after use to prevent the tips from drying out.

What to consider before purchase

• Permanent pigment ink is not easily erasable; consider erasable pens if you need removable lines
• Tip sizes are fixed; check the supplied range to ensure it meets your required line widths
• Paper type affects ink behaviour — test on your preferred paper if precise appearance is critical

Usage recommendations

For archival-quality linework, start with the finer tips for construction and detail, then switch to mid and thicker sizes for emphasis and shading. When combining with watercolour, ensure ink has dried completely to preserve line integrity. Store pens horizontally or capped upright and recap immediately after use to maintain consistent performance across the set.
