Uni-Ball UB-157 Eye Fine 0.7mm Pen - Red 12-pack RB-UB157-RED
The Uni-Ball UB-157 Eye Fine is a capped liquid-ink rollerball designed for clear marking, corrections and everyday handwriting. Its 0.7 mm tungsten-carbide ball produces an approximately 0.50 mm writing line, while Uni-Ball’s controlled ink-flow system supplies red ink evenly throughout the life of the pen.

Clear Red Writing
The 0.7 mm rollerball provides a defined red line suited to marking, proofreading, corrections, annotations and colour-coded notes. Its approximately 0.50 mm writing width offers clear visibility while retaining the control required for detailed comments.

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 marking or writing task.
Water-Resistant Red Pigment Ink
The red 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 corrections, annotations and written information remain clear over time.

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