Usage
The Uni-ball Eye Fine roller Eco is designed for precise writing and note-taking in professional, academic, or everyday contexts. Its turquoise ink and 0.5 mm line width make it suitable for color-coding, organizing information, or creative tasks.
Advantages
- Produces consistent, fine 0.5 mm lines ideal for detail work and legible notes[2][6].
- Smooth liquid ink flow thanks to the uni-Flow system ensures uninterrupted writing from beginning to end[5][7].
- Waterproof, fade-resistant Uni Super Ink protects documents against smudging and environmental damage[1][3][6].
- Eco-conscious design made with up to 75% recycled plastic material—10% sourced from ocean waste—lowering environmental impact[2][10].
- A visible ink window on the barrel lets you monitor remaining ink at a glance[1][5].
Specifications
- The pen features a durable stainless steel tip (nib size: 0.7 mm) that creates a measured line of approximately 0.5 mm width; the body is crafted mainly from recycled plastic (up to 75%, including ocean-sourced plastics)[1][2].[10]
- Permanence: The quick-drying Uni Super Ink is both waterproof and resistant to fading or tampering; suitable for archival-quality documentation[3][6].[9]
- The pen writes a continuous fine line (approximate width: 0.5 mm), with smoothness maintained by the UNI-Flow controlled delivery system; estimated weight per pen about ~13 g[2]. Actual lifespan depends on usage but outlasts many conventional gel pens due to controlled flow.
- Differentiators include an eco-friendly build with significant recycled content, non-refillable capped design for reliability, ergonomic barrel shape, pocket clip cap for portability, turquoise color variant suitable for creative applications.[1][7]
How it works
This rollerball pen uses liquid ink delivered through a precision stainless steel tip via the uni-Flow system. The even distribution ensures every stroke remains clear until the last drop of ink while its see-through window keeps you aware of your supply.[1][5]
