Fineliner pen SMARTMAX SmartMax Fineliner sepia 0,1 mm — technical drawing and sketching pen

SMARTMAX SmartMax Fineliner sepia 0,1 mm is a precision fineliner designed for technical drawing, detailed sketching and fine handwriting. The ultra-fine 0.1 mm metal-clad tip produces consistent, narrow sepia lines with controlled ink flow, suitable for work on paper, tracing paper and notebooks. The pen is intended for users who need accurate line definition and uniform stroke width for illustrations, diagrams and written notes.

Advantages

The fineliner tip provides high precision and stable ink distribution to reduce skipping and feathering. Sepia ink offers a warm, neutral tone that complements technical drawings and artistic sketches while remaining legible for annotations. Its lightweight barrel and balanced grip enable extended use with minimal hand fatigue, and the durable tip maintains shape for reliable line width over time.

How to use

Uncap the pen and test the line on a scrap of the same paper you will use to check ink appearance and bleed. Hold the pen at a comfortable angle and apply light, even pressure to maintain the 0.1 mm line width; heavier pressure may widen the stroke slightly. For technical work, use rulers and templates to guide straight lines and maintain consistent spacing. Recap the pen after use to prevent the tip from drying out.

Usage recommendations

Store the fineliner horizontally or with the cap on to preserve ink flow. For archival-quality results, test compatibility with your paper and consider using heavier, bleed-resistant paper for ink-intensive work. For mixed-media pieces, allow the sepia ink to dry fully before applying water or other wet media.
