Compared to other Eye Micro Rollerball pens, the 150 with a 0.5mm tip focuses on precision and a waterproof green ink variant. Other options may offer different ink colors (e.g., black or blue) or slight tip variations. If you’re choosing by color or availability, you can explore similar specs for Black or Blue variants on Fepy.

Ideal for precise note-taking, journaling, professional documentation, and forms where neat, legible writing is important. The waterproof ink helps prevent smudges in sheets that might get damp or exposed to moisture.

Write with a light, steady hand to maximize line consistency. Keep the cap on when not in use to prevent the ink from drying. If the ink flow slows, gently revitalize by writing a few strokes on scrap paper. Store capped and away from extreme heat to maintain tip longevity.

This pen uses waterproof ink and standard writing-instrument materials that are commonly used in office and school settings. It is designed for regular handling and writing; keep away from small children who might attempt to put it in their mouth.

The Uni-ball Eye Micro Rollerball line is typically designed for reliable single-pen usage with replaceable refills in some markets. Check the specific availability on Fepy for refill options compatible with the UB-150 model if you prefer continued use.

Page yield depends on writing pressure and usage. With a 0.5mm tip and smooth flow, you can expect steady writing for many pages before the ink begins to run low. If you’re doing heavy note-taking, you might reach the refill limit sooner; light journaling will last longer.
