Technical Drawing Pen Rystor 0.20 mm Black - precision fine-line drafting pen

Rystor technical drawing pen with a 0.20 mm black tip is designed for precision fine-line drafting and detailed technical illustrations. The pen features a consistent polyester/metal tip that produces uniform 0.20 mm lines and a controlled ink flow formulated for clean, smudge-resistant results. Its compact form and stable ink delivery make it suitable for scale drawings, schematics, annotations and any work requiring exact line width and clarity.

Advantages

The precise 0.20 mm tip ensures reproducible fine lines while the combined polyester and metal tip construction provides durability and stable performance over extended use. Black archival-style ink offers strong contrast on technical papers and tracing films and resists feathering for clear, sharp details. The pen’s controlled flow prevents blotting and supports continuous drawing without frequent interruptions.

Suitable for

• Architectural and engineering scale drawings
• Technical schematics and circuit diagrams
• Detailed illustrations and line art
• Annotations, labeling and drafting on tracing paper
• Precision graphic work and CAD hand-sketching

Key specifications

How to use

Remove the cap and hold the pen at a comfortable angle to maintain consistent contact between the tip and the drawing surface. Use steady, even pressure to produce uniform 0.20 mm lines; avoid pressing excessively to protect the tip. For best results, test the line on a scrap of the same paper before starting detailed work. Replace the cap after use to prevent ink drying and store horizontally or with the cap up to maintain optimal ink flow.

Usage recommendations

For accurate, long-lasting results, pair the pen with high-quality technical drawing paper or tracing film, keep a spare pen for continuous projects, and avoid heavy erasing over drawn lines to preserve tip integrity and line clarity.
