The Rotring S0699370 technical pen set includes a mechanical pencil and three technical pens with 0.2 mm, 0.3 mm and 0.5 mm line widths. Designed for precise drawing and writing, the set provides consistent black ink flow and fine line control suitable for technical drawings, architectural plans, illustrations and detailed sketches. The components are arranged to support accurate line work and reproducible results when working on paper and drafting film.

Advantages

The set combines a mechanical pencil with three size-specific technical pens to cover a range of line widths without requiring multiple separate purchases. The pens deliver sharp, clear black lines with stable ink flow that reduces blotting and interruptions. The mechanical pencil offers precise lead placement for guidelines and measurements, while the pens are engineered for durability and repeatable line quality in professional and student work.

How to use

Use the mechanical pencil to draw initial construction lines and measurements, then trace final lines with the appropriate technical pen size for the required line weight. Hold the pens at a steady angle and move the sheet rather than the tip for longer straight lines when possible. Cap the pens after use to prevent ink drying and store them horizontally if recommended by the manufacturer for extended periods.

Recommendations

Choose the 0.2 mm pen for very fine details and lettering, 0.3 mm for medium line work and hatching, and 0.5 mm for outlines and bolder lines. Allow ink to dry before erasing pencil guidelines and test on scrap paper to confirm line weight and drying time for the specific paper you use.
