Uni-ball EYE

The Uni-ball EYE liquid ink rollerball pens have been amongst the best of their type ever since their launch in 1994. The stainless-steel tip with tungsten-carbide ball, fed by an ink controller system, ensures consistent and reliable lines. The ink itself is unusual in being waterproof pigment ink and part of Uni's Super Ink series of high-quality, high-security ink.
