Description

The Uniball Micro-Air ballpoint pen gives you the freedom of a fountain pen with the security of a roller-ball with no leaks. Unlike other rollerballs, the Air’s metal ball is held in a plastic surround, allowing the ball to move without friction when the pen is held at an angle. It is filled with Uni-Ball Super Ink, an advanced ink formula that bonds to paper fibers. It is resistant to chemicals that wash dye-based ink from checks. Super ink is also fade resistant, water resistant, and acid free. Applying light pressure will give a finer line as ink is transferred by the ball itself, whilst firmer pressure allows the ink to flow freely around the ball for a thicker line. The Micro- air pen will give you a finer line width between 0.25mm - 0.45mm, perfect for technical writing or small printing. The sleek, elegant look and feel that is comfortable and easy to grip, and the capped top stays put and ensures that this pen will never leak in your pocket. Black Ink in a Box of 12.

Was finally able to find a pen that was water resistant. They write very smooth, and are perfect for journaling.

  • NO BOX for the uni-ball Micro Air Pen
Style: 12 Blue
I am changing pens after over 20 years of using a different brand. Somehow ended up with one of these (in black - though blue is my favorite ink color) and liked it so much that when my last "fav" blue pen died; I ordered a dozen of these. Was pretty surprised that they arrived in a plastic bag and not a box. I ordered supplies for a courthouse for years--pens came in a box; so they were easy storage. A Minor complaint as the pen, itself, seems like it could become a "new" favorite! I honestly DO like the way it writes. But, if you are ordering for an office, just keep in mind, they may not come in a box. ... show more

  • Makes fountain pens more everyday
Changing reading to 5 starts. While the ink doesn't dry quickly, the pen is easy to use. These are far less messy that a "real" fountain pen. I like them and will buy again.
