أقلام يوني بول آي ميكرو رولر (0.5mm) تحكم فائق الدقة، كتابة واضحة وسلسة، مثالية للاستخدام في المكتب والمنزل والمدرسة، لون أسود ضمن عبوة من (12) قلم

Point size: 0.5 mm. Ink: archival pigment ink that resists water and fading. Inks flow: uni-flow regulation for smooth, consistent lines. Cap: secure snap-cap to protect the tip. Barrel feature: level gauge window to monitor ink level. Pack: 12 pens in black.

Uni-flow regulation ensures a consistent ink supply with minimal pressure, reducing skips and producing steady lines even with varied writing speeds.

The window lets you visually estimate remaining ink, helping you plan replacements before important sessions or exams.

Cap the pen when not in use to protect the tip. Write with a light, even pressure for consistent lines. If you notice skipping, try a fresh capful of ink by replacing the cap firmly, and keep the barrel window in view to gauge remaining ink.

Yes. The pigment ink is designed to resist water and fading, helping your written records stay readable longer and offering better durability for everyday archival-like notes.

They’re well-suited for precise annotations in technical notes, detailed diagrams, forms and checklists, office labeling, school notes, and any task requiring fine, crisp lines.

Store capped when not in use, upright if possible, in a cool, dry place away from direct sunlight and extreme heat. Avoid harsh conditions that can dry out or bleed the ink.

They’re designed for everyday writing and office/school use. Keep caps on when not in use to prevent tip damage or ink leakage, and keep away from small children to avoid choking hazards.

A 12-pack provides multiple pens for shared stations, classrooms, or multiple workspaces, making it a convenient and cost-effective option for ongoing use without frequent replacements.

The product listing describes a 12-pack rather than a refillable nib system. Replacements would typically be purchased as new 12-pack sets rather than individual refills.
