Summary:

The Uni-Ball Eye Fine UB-157 dispenses liquid pigment ink through a 0.7mm stainless steel tip. This rollerball pen produces a 0.5mm line width using an internal regulator to control ink flow. The Uni-Flow system maintains constant pressure for consistent writing until the reservoir is empty.

Key Features

Uni-Flow Pressure System: Internal regulator feeds ink consistently from the reservoir to the tip. Skips don't occur even when writing at high speeds.
Uni Super Ink: Pigment-based formula bonds with paper fibers to resist chemical washing. Ink stays legible if the paper gets wet.
Tungsten Carbide Ball: 0.7mm ball material resists wear and maintains a round shape. The tip won't scratch paper or leak under pressure.
Polypropylene Barrel: High-density plastic housing includes a clear window for monitoring ink levels. You won't run out of ink unexpectedly.
Fade-Proof Green Ink: Acid-free liquid pigment maintains color saturation over long periods. Notes remain readable despite high humidity and sunlight exposure.
