## Description

Uni-Ball UBA-188-M Fountain Pen Tip 0.5mm Air Rollerball Pens, Red Gel, 12 Pack

## Features

- The freedom of a fountain pen without leaking: the unique metal ball of this model moves without friction, no matter what angle the pen is held.
- The ballpoint pen is filled with Uni-Ball Super Ink, an advanced ink formula that bonds to the paper fibres. Never fade, waterproof and acid free.
- Lower pressure creates a thinner line as the ink is transferred directly over the ball. With stronger pressure, more ink flows around the ball and the line becomes thicker.
