Brush tip pen PENTEL Pentel Brush Sign Pen Twin SESW30 — brush marker, felt tip, model SESW30C-T125

PENTEL Brush Sign Pen Twin SESW30 (model SESW30C-T125) is a brush-tip marker created for lettering, illustration and sketching on paper. The pen combines a flexible brush-style felt tip that produces varied line widths with a consistent ink flow designed for clear, saturated strokes. Its form factor supports precise control for both fine details and broader expressive marks, making it suitable for hand lettering, signmaking and detailed drawing work.

Advantages

The flexible brush tip adapts to pressure and angle, enabling smooth transitions between thin hairlines and broader brush strokes without the need to change tools. The felt construction provides reliable ink delivery and good edge definition on standard drawing papers. The pen’s balanced body supports comfortable handling during extended use, and the single-color, high-contrast ink improves legibility and scan reproduction for reproductions and digital capture.

Suitable for

• Hand lettering and modern calligraphy
• Illustration and sketching
• Signmaking and poster text
• Detail work in design mock-ups
• Practice exercises for pen control and stroke variation

Key specifications

• Tip type: flexible brush-style felt tip for variable line width
• Ink characteristics: high-contrast, consistent flow suitable for paper
• Body: lightweight pen body designed for comfortable grip and control
• Suitable surfaces: paper and similar porous drawing substrates
• Typical uses: lettering, sketching, illustration, sign text

How to use

Hold the pen at different angles and vary pressure to produce a range of line widths: lighter pressure for hairlines and increased pressure for broader strokes. For lettering, begin with basic strokes to warm up and practice consistent pressure transitions. When sketching or illustrating, use the tip’s flexibility to achieve expressive line variation and edge contrast. Store the pen capped when not in use to prevent the felt tip from drying out and to maintain consistent ink flow.

Usage recommendations

Use smooth, medium-weight papers intended for marker or mixed-media work to minimize feathering and bleed-through. Test the pen on a scrap sheet before applying to final artwork. For precise outlines, combine the brush pen with fineliners or technical pens; for fills, consider layering strokes gradually to avoid oversaturation of the paper.
