Note-taking in class or meetings, precise journal entries, drafting professional documents, technical sketches, and any writing task that benefits from clean lines and reliable ink without smearing.

Uncap the pen and begin writing. If you notice skipping, ensure you’re using a fresh ink cartridge compatible with UB-150. Store tip-down or horizontally to prevent ink from pooling in the nib. If the ink flow slows, try writing on paper with a bit more weight to encourage a consistent line, and replace the cartridge if needed.

Yes, the ink is blue and waterproof once dry, helping protect written documents against spills. The pen is designed for everyday writing use and provides a non-smearing, durable finish suitable for notes, journaling, and professional documents.

It combines a precise 0.5 mm tip with waterproof blue ink, a transparent ink window for easy monitoring, and a comfortable grip—all in a durable, well-regarded UB-150 design. This balance of precision, reliability, and usability often translates to lower long-term writing fatigue and fewer re-writes, offering strong value against similar pens.

The UB-150 Eye Micro Rollerball is designed with a fixed 0.5 mm tip for consistent precision. If you need a different tip size, consider a different model in the Uni-ball line rather than swapping nibs on this pen.
