أقلام يوني بول يوني بين فاين لاينر (0.5mm) حبر صبغي أرشيفي، كتابة دقيقة وسلسة، مثالية للرسم والكتابة التقنية لون أسود

Archival pigment ink is water- and fade-resistant, so lines stay legible and dark over long periods, even with repeated handling.

The metal-clad tip provides extra durability, keeps a consistent line when you guide the pen along edges, and helps prevent tip wobble on straight lines.

No. The quick-setting pigment dries rapidly to reduce smudging, making it suitable for tidy overwriting and clean scans.

0.5 mm tip, archival pigment ink, waterproof and fade-resistant, metal-clad tip, smudge-resistant, snap-cap for cap-on cap-off use.

Technical drawing, architectural notes, precise labeling, notebook journaling, and detailed line work on sketches.

Keep the cap on when not in use, store upright to protect the tip, and use on smooth, clean paper to minimize tip wear and ink feathering.

For finer lines, try the Uni Pin 0.3 mm fineliner; for thicker lines, the Uni Pin 0.8 mm fineliner. See product pages: https://fepy.com/product/uni-pin-fineliner-0-3-mm-black and https://fepy.com/product/uni-pin-fineliner-0-8-mm-black

Both offer crisp lines, but Uni Pin uses a pigment-based archival ink with a metal-clad tip designed for durable lines on rulers, while Pigma Micron is another popular archival ink option. See: https://fepy.com/product/pigma-micron-05-mm-black

Most Uni Pin fineliners are not designed to be refilled; once empty, the entire pen is typically replaced.

The family includes multiple tip sizes (e.g., 0.3 mm, 0.5 mm, 0.8 mm) to cover fine details and broader line work. Check product pages for current availability.
