Rystor Cienkopis RC-04 gray — Rystor RC-04 fine line pen, gray

Rystor Cienkopis RC-04 gray is a fine line pen designed for precision writing and drawing. The gray ink and narrow tip provide controlled, consistent lines suited to detailed notes, sketches and technical illustrations. The pen is intended for everyday use in office, school and hobby environments where accurate ink flow and a slim stroke are required.

Advantages

The slim tip produces a uniform, fine line that helps maintain legibility in small handwriting and detailed drawings. The gray ink offers a softer contrast than black while remaining clearly visible on white and off-white papers. The body is lightweight and balanced for extended use, and the ink formulation delivers steady flow to reduce skipping during continuous strokes.

Suitable for

• Technical drawings and schematics
• Detailed sketches and illustrations
• Note-taking, annotations and margin text
• Bullet journaling and planners

Key specifications

• Tip type: fine point for narrow line width
• Ink color: gray
• Line consistency: steady flow designed to minimize skipping
• Body: lightweight construction for comfortable handling

How to use

Remove the cap before writing and hold the pen at a comfortable angle of about 45 degrees for optimal ink delivery. Apply light, even pressure to maintain a consistent fine line; heavier pressure may produce a wider stroke. Store capped when not in use to prevent drying and shake gently if necessary to restore flow after long storage.

Usage recommendations

Use on standard paper types for best results; test on specialty or glossy papers first. For archival work or documents requiring higher contrast, consider combining the gray fine line with a darker pen. Replace or recap the pen after extended pauses to maintain consistent performance.
