Uni-Ball UB-157 Eye Fine 0.7mm Pen - Green 12-pack RB-UB157-GRN
The Uni-Ball UB-157 Eye Fine is a capped liquid-ink rollerball designed for clear writing, annotations and colour-coded notes. Its 0.7 mm tungsten-carbide ball produces an approximately 0.50 mm writing line, while Uni-Ball’s controlled ink-flow system supplies green ink evenly throughout the life of the pen.

Clear Green Writing
The 0.7 mm rollerball provides a defined green writing line suited to annotations, planners, diagrams, study notes and colour-coded document work. It offers a slightly fuller line than the Eye Micro while retaining the control needed for clear handwriting.

Continuous Uni-Flow Ink Delivery
Uni-Ball’s uni-flow system regulates the liquid ink supply to maintain consistent line density and smooth writing through to the last drop. A visible window in the barrel allows the remaining ink level to be checked before beginning an important task.
Water-Resistant Green Pigment Ink
The green Uni-Ball Super Ink uses a pigment formulation designed to resist water and fading. Uni-Ball also describes its Super Ink as tamper-resistant, helping notes, records and colour-coded information remain clear over time.

Durable Rollerball Construction
The 0.7 mm tungsten-carbide ball is housed in a stainless-steel tip for dependable everyday writing. Green colour coding on the cap and tip identifies the ink colour, while the removable safety cap protects the writing point between uses.
