قلم يوني بول (Uni Pin) ذو الخط الدقيق برأس (0.1mm) حبر سلس لون رمادي داكن

Tip size: 0.1mm. Ink color: dark grey. Flow: smooth and consistent. Tip durability: designed for long use. Pack: single pen. Practical uses include sketching, illustrations, and precision writing.

A 0.1mm tip creates extremely fine, precise lines with high detail. Thinner tips like 0.1mm produce sharper edges and are better for technical drawings, while thicker tips (e.g., 0.3–0.5mm) yield bolder lines and faster coverage.

Fine-line pens like this perform well on smooth, bleed-resistant papers such as marker paper, bristol board, and high-quality notebook paper. If your paper is very rough or highly absorbent, lines may appear lighter or feather slightly.

The ink is a professional, subtle dark grey that stands out clearly on light papers while remaining understated and legible on various backgrounds, making it suitable for technical drawings and professional notes.

Store cap closed when not in use. Use a light touch to avoid excessive pressure that could fray the tip. Test on scrap paper before finalizing a line, and keep the tip clean and dry for consistent ink flow.

Keep the cap on when not in use and store the pen horizontally or with the tip slightly upward to prevent ink leakage. Avoid extreme heat and keep the tip clean to maintain smooth ink flow.

Architectural and technical drawings, detailed sketches, precise lettering, and any work requiring crisp, fine lines with a professional dark-grey tone.
