Review: The writing look professional - Thw writing is very comfortable Review: As expected - These don’t come in Uni ball Packaging. Instead they come in a plastic sleeve. I assume they are taken from a bill pack broken down and sent out. But they seem ok ! ## 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. - 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. - The 0.5mm ball delivers a line width of between 0.28mm and 0.45mm (dependent on pressure). - 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. - Contains 1 Black, 1 Blue, 1 Red Ink Pens ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01FI1MPAI | | Additional Features | Liquid Ink | | Age Range Description | All Ages | | Animal Theme | no animal theme | | Best Sellers Rank | #2,787 in Office Products ( See Top 100 in Office Products ) #27 in Liquid Ink Rollerball Pens | | Body Shape | Round | | Brand Name | uni-ball | | Closure Type | Click-Off Cap | | Color | multi | | Customer Reviews | 4.5 4.5 out of 5 stars (1,217) | | Drill Point | Fine | | Grip Type | Standard | | Hand Orientation | Ambidextrous | | Hardness | HB | | Included Components | 3 pens (Black, Blue, Red) | | Ink Base | Water | | Ink Color | Blue | | Item Diameter | 0.5 Millimeters | | Item Dimensions | 25 x 25 x 127 millimeters | | Item Type Name | Stick | | Item Weight | 1 Ounces | | Line Size | 0_28mm_and_0_45mm | | Manufacturer | uni-ball | | Material Type | Metal | | Model Name | Air Micro | | Model Number | Air Micro | | Recommended Uses For Product | Writing, Note-taking, Drawing | | Style | Contemporary | | Theme | People | | Unit Count | 3.0 Count | | Water Resistance Level | Water Resistant | | Writing Instrument Form | Roller Ball Pen | ## Product Details - **Age range (description):** All Ages - **Brand:** uni-ball - **Colour:** multi - **Ink colour:** Blue - **Writing instrument form:** Roller Ball Pen ## Images ![Uni-Ball AIR Micro - 0.5mm Fine Rollerball - Pack of 3 - Black, Blue, and Red - UBA-188-M - Image 1](https://m.media-amazon.com/images/I/71JG1AvzwWL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ The writing look professional *by A***D on 16 December 2025* Thw writing is very comfortable ### ⭐⭐⭐⭐⭐ As expected *by T***O on 2 September 2022* These don’t come in Uni ball Packaging.
