Technical Drawing Pen Rystor CK-05 blue - fine-line draughting instrument

Rystor CK-05 blue is a technical drawing pen designed for precise fine-line drafting and detailed illustration. The pen produces a consistent blue stroke suitable for use with rulers, templates and drawing boards. It is intended for technical drawings, architectural sketches, diagrams and artwork where accurate, repeatable lines are required. The ink flow and tip construction support controlled lines and minimal feathering on technical paper.

Advantages

The CK-05 delivers even ink distribution and stable line width for repeatable results across multiple drawings. Its fine tip is engineered to produce crisp edges that work well with straightedges and drafting tools. The formulation of the ink reduces bleeding and shows predictable drying behavior on drafting and marker papers. The pen’s body provides a comfortable grip for extended use and allows precise maneuvering for detailed work.

Suitable for

• Technical and engineering drawings
• Architectural and construction sketches
• Diagrams, schematics and flowcharts
• Detailed illustrations and ink line work
• Student drafting and design exercises

Key specifications

• Ink color: blue
• Line type: fine-line for draughting
• Tip: precision fine point designed for rulers and templates
• Ink properties: consistent flow, low feathering, quick-drying on technical paper
• Body: ergonomically shaped for controlled handling during extended use

How to use

Before starting a drawing, shake the pen gently if recommended by the manufacturer, then test the stroke on scrap paper to confirm the ink flow. Use the pen with appropriate drafting tools such as rulers, templates and drawing boards to achieve straight or repetitive lines. Apply steady, even pressure for uniform strokes; avoid pressing too hard to prevent tip damage or excessive ink deposition. Close the cap securely after use to prevent the tip from drying.

Usage recommendations

For best results, use on papers intended for technical pens or marker use, and allow a short drying interval before erasing pencil guides. Store horizontally or with the tip down for short periods to maintain consistent ink flow. Replace the pen according to visible wear of the tip or changes in line quality.
