Its acetal plastic-encased metal ball ensures smooth ink flow that intensifies with pressure. Equipped with Uni’s high-quality Super Ink, the pens offer water, fade, and tamper resistance, making them ideal for secure, professional writing. This pack of six blue ink pens combines innovation and reliability for the discerning professional.

## Description

Description The metal ball of the nib is encased in an acetal plastic, rather than the standard metal surround, which allows for a smoother flow of ink around the ball, and an increased flow as further pressure is applied.

## Features

- The revolutionary tip of the sky, unlike conventional rollerballs, is pressure sensitive, meaning it gives a writing experience and differentiating line width similar to that of a fountain pen.
- The metal sphere of the tip is enclosed in an acetal plastic, rather than the standard metal sheath, which allows for smoother flow of ink around the ball, and increased flow as further pressure is applied.
- The 0.7 mm ball delivers a line width between 0.35 mm and 0.55 mm (depending on pressure).
- Properties Uni's high quality "Super Ink", which is not only water and fade-resistant, but also "Tamper-Resistant", which means that the ink cannot be washed off with chemicals and solutions used by people to modify fraudulent documents.
- Pack contains 6 blue ink pens.
