Uni-Ball UB-150 Eye Micro 0.5mm Pen - Green 12-pack RB-UB150-GRN
The Uni-Ball UB-150 Eye Micro is a capped liquid-ink rollerball designed for fine, precise handwriting, colour coding and detailed annotations. Its 0.5 mm tungsten-carbide ball produces an approximately 0.30 mm writing line, while Uni-Ball’s controlled ink-flow system supplies green ink evenly throughout the life of the pen.
Fine Green Writing
The micro rollerball produces a narrow green line suited to notes, annotations, planners, diagrams and colour-coded document work. Its approximately 0.30 mm writing width helps keep smaller handwriting and detailed markings clear.

Consistent Uni-Flow Ink Delivery
Uni-Ball’s uni-flow system regulates the liquid ink supply for consistent line density and smooth writing through to the last drop. A visible window in the barrel makes it easy to check the remaining ink level before starting a writing 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 written information remain clear and making the pen useful for records, colour coding and everyday document work.

Durable Rollerball Construction
The 0.5 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.
