Technical Drawing Pen Rystor 0.80 mm Black - precise ink line for drafting

Rystor technical drawing pen with a 0.80 mm tip in black ink is designed for drafting, technical drawings and graphic work. The pen produces a consistent medium-thick ink line that suits diagrams, sketches, plans and annotations. Its durable tip and controlled ink flow provide predictable results on paper and drafting film, offering steady line width for detailed work and routine tasks.

Advantages

The 0.80 mm tip delivers uniform, medium-thick lines that remain visible without excessive bleed. The black pigment ink dries quickly and resists smudging, supporting clean overlays and inked measurements. A robust nib construction minimizes tip damage under normal drawing pressure, while the consistent feed reduces skipping during continuous strokes.

Suitable for

• Architectural and engineering drawings
• Technical diagrams and schematics
• Sketching and concept drafting
• Annotating plans and documentation
• Illustration work requiring steady medium-width lines

Key specifications

• Tip size: 0.80 mm
• Ink color: black
• Ink type: pigment-based, quick-drying
• Line quality: consistent medium-thick line, low bleed
• Suitable surfaces: paper, drafting film, tracing paper

How to use

Hold the pen at a comfortable angle and apply light, even pressure to maintain the 0.80 mm line width. For best results, test on a scrap of the same paper to confirm ink behavior and drying time. Replace caps after use to prevent the tip from drying out. When drawing long continuous lines, keep a steady hand and maintain a consistent stroke speed to avoid pooling or skips.

Usage recommendations

Store the pen horizontally or tip-up when not in use to preserve ink flow. Use with archival or coated papers for optimal line crispness. Avoid pressing excessively to extend nib life and achieve the intended medium-thick line width.
