Uni-ball Eye Micro Roller Pens, 0.5 mm, Ultra-Fine Control, Smooth Writing, Ideal for School, Office & Home Use, Blue – Pack of 12

A 0.5 mm micro tip produces finer, more compact lines, which helps with dense note-taking, tight forms, and precise diagrams. It’s ideal when you want legible text without large ink blobs and when drawing small boxes or form fields.

The pens use pigment ink that is water- and light-resistant to help your lines stay clear over time. This makes the writing more durable for long-term notes and documents.

The Uni-flow system regulates ink flow to deliver smooth, even strokes with minimal skipping. This means you get consistent lines without having to press hard or redraw over the same area.

The window lets you see the remaining ink at a glance, so you know when it’s time to replace the pen before it runs dry.

It’s great for students, teachers, and professionals who need reliable blue 0.5 mm writing for note-taking, forms, field notebooks, and technical diagrams. The pack size keeps a pen handy at different locations—desk, backpack, and classroom kits.

Cap the pen when not in use to protect the tip, and store in a cool, dry place. The cap helps prevent the nib from drying out and protects against accidental marks in pockets or bags. The ink window helps you monitor ink levels to avoid mid-writing interruptions.

Yes, writing instruments from Uni-ball are designed for general school, office, and home use. They are considered non-toxic and suitable for everyday writing; as with any small part, keep away from very young children who might swallow components.

These Eye Micro Roller pens are generally sold as disposable units. When the ink runs out, you would replace the pen with a new one or choose a refillable option if available from Fepy’s lineup.

Buying in a 12-pack offers a lower per-pen cost, reduces the need to reorder frequently, and ensures there are backups for multiple users or locations (desks, bags, and classrooms). The pack is especially economical for study groups, offices, or households that rely on consistent blue ink for documents and notes.

Maintain light, consistent pressure for clean lines with the 0.5 mm tip. Let the ink flow freely—avoid pressing too hard, which can cause line variation or skip. If you notice a slight skip, gently lift and reapply with even pressure to resume a continuous line.
