Brush marker PENTEL Pentel Brush Sign Pen Artist SESF — fine flexible nylon tip, water-based ink

PENTEL Brush Sign Pen Artist SESF is a brush-style marker with a fine flexible nylon tip and water-based ink. Designed for lettering, illustration and sketching, the pen offers a responsive tip that adapts to pressure and stroke speed to produce a wide range of line widths from hairline to expressive strokes. The water-based ink dries quickly on most paper types and is suitable for detailed drawings, calligraphy practice and mixed-media sketches where a controlled brush effect is required.

Advantages

The fine flexible nylon tip combines the control of a pen with the expressive capabilities of a brush, allowing for consistent thin lines and smooth transitions to broader strokes. Water-based ink provides clean, even coverage with minimal bleeding on quality paper and is easy to layer or combine with water media. The pen’s compact, lightweight body is convenient for hand lettering sessions and portable sketching, while the durable tip retains spring and shape over extended use.

Suitable for

• Hand lettering and modern calligraphy practice
• Illustration and ink sketches
• Detail work in mixed-media and design drafts
• Sketchbooks, journals and paper-based art projects

Key specifications

• Tip type: fine flexible nylon brush tip
• Ink type: water-based ink
• Line width: variable depending on applied pressure and stroke
• Ideal surface: paper and paper-based sketchbooks
• Body: lightweight, pen-style barrel for handheld control

How to use

Hold the pen at a comfortable angle and apply light pressure for thin, precise lines; increase pressure and alter stroke direction to create thicker, expressive strokes. Work on smooth, absorbent paper for best results and allow ink to dry between layers when combining with other media. Cap the pen after use to prevent the tip from drying out and store horizontally or tip-up when possible to maintain consistent ink flow.

Usage recommendations

For lettering practice, warm up with basic upstrokes and downstrokes to condition the tip. Test on a scrap of the same paper before starting a final piece to check bleed and drying time. When combining with watercolour or water-based washes, wait until the ink is fully dry to avoid unintended bleeding.
