Uni-Ball AIR Micro Rollerball Pens - 0.5mm Fine Tip - Blue Ink - Pack of 4 - Assorted Colors

Uni-Ball presents a set of four Liquid Ink Rollerball Pens, each filled with blue ink and featuring barrels in four vibrant colors: Pink, Orange, Green, and Light Blue. The Air model boasts a revolutionary nib design that sets it apart from traditional rollerballs. This pressure-sensitive nib offers a writing experience akin to using a fountain pen, with the added bonus of creating varying line widths.

Unlike standard rollerball pens, the Air's metal ball is enclosed in acetal plastic rather than metal, allowing for a smoother ink flow and increased flow with more pressure. The 0.5mm ball produces lines ranging from 0.28mm to 0.45mm in width, depending on the pressure applied while writing.

Uni's proprietary "Super Ink" is featured in these pens, providing water and light resistance as well as "Tamper-Resistant" properties. This means that the ink cannot be removed using common chemicals or solutions, making it ideal for preventing fraudulent document alterations.

This set includes four pens, each with blue ink and a barrel color matching one of the following: Pink, Orange, Green, and Light Blue. Experience the innovation and quality of Uni-Ball with these stylish and functional rollerball pens.
