Waterproof red ink resists smudging when exposed to moisture, helping your notes and documents stay legible and durable even after spills or humidity. It’s especially useful for archival-style notes, legal or lab paperwork, and field work.

The transparent ink barrel lets you quickly see how much ink remains, so you can plan when to replace or have a spare handy and avoid surprises during important writing sessions.

A 0.5mm tip provides fine, sharp lines with good control, ideal for neat handwriting, small margins, and detailed documentation. It reduces the likelihood of broad strokes and ink bleed on standard paper.

Yes. The UB-150 is designed with an ergonomic grip to reduce hand fatigue during extended writing, making it suitable for note-taking, journaling, and professional use.

The ink is designed for general writing use in offices, schools, and homes. It’s formulated to be non-toxic for everyday writing tasks, but always handle with standard care and avoid ingestion.
