Uni-Ball UB-157 Eye Fine 0.7mm Pen - Blue 12-pack RB-UB157-BLU
The Uni-Ball UB-157 Eye Fine is a capped liquid-ink rollerball designed for clear, consistent 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 blue ink evenly throughout the life of the pen.

Clear, Consistent Writing
The 0.7 mm rollerball provides a defined blue writing line suitable for everyday notes, correspondence, forms, reports and longer written documents. It offers a slightly fuller line than the Eye Micro while retaining the control needed for neat 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 barrel window allows the remaining ink level to be checked before beginning an important task.
Water-Resistant Blue Pigment Ink
The blue Uni-Ball Super Ink uses a pigment formulation designed to resist water and fading. Uni-Ball also describes its Super Ink as tamper-resistant, making this pen a practical option for records, forms, study notes and other writing that may need to 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. Blue colour coding on the cap and tip identifies the ink colour, while the removable safety cap protects the writing point between uses.
