## Description

Uni-Ball AIR Micro - 0.5mm Fine Rollerball - Blue Ink - Assorted Barrels - 5 Pack

Review: Not as expected - Pen 1: Leaks ink. Pen 2: Ink doesn’t come out evenly, so you have to rewrite some words. Pen 3: The pen cover was cracked, so you swapped it with a cover from one of the pens that didn’t work. So far is good. Pen 4: Haven’t used yet. Pen 5: Haven’t used yet. Pen 6: Haven’t used yet.
Review: Items well received - Received xactly as described.

## Features

- The revolutionary nib of the Air, unlike conventional rollerballs, is pressure sensitive, meaning that it gives a writing experience and differentiating line width similar to that of a fountain pen
- Pack contains five Blue inked pens, in each of the following barrel colours: White, Blue, Green, Orange, and Pink
- 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 Uni's high quality "Super Ink", which is not only water and light resistant, but also "Tamper-Resistant", meaning that the ink cannot be washed off using chemicals and solutions used by people to fraudulently modify documents
