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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07BSNH6N5 | | Best Sellers Rank | #8,021 in Office Products ( See Top 100 in Office Products ) #81 in Liquid Ink Rollerball Pens | | Brand | AIR Micro | | Closure | Click-Off Cap | | Color | r.blue | | Customer Reviews | 4.1 4.1 out of 5 stars (4) | | Date First Available | 11 March 2019 | | Grip Type | Smooth | | Ink Color | Blue | | Item Weight | 50 g | | Line Size | 0.5mm | | Manufacturer | AIR Micro | | Manufacturer Part Number | UBA-188EL-M | | Material Type | Plastic Metal | | Model number | UBA-188EL-M | | Number of Items | 5 | | Point Type | gear head | | Product Dimensions | 13.49 x 5.21 x 0.99 cm; 50 g | | Size | 5 Count (Pack of 1) | ## Product Details - **Age range (description):** Adult - **Brand:** AIR Micro - **Colour:** r.blue - **Ink colour:** Blue - **Writing instrument form:** Roller Ball Pen ## Images ![Uni-Ball - 0.5mm Fine Rollerball - Blue Ink - Assorted Barrels - 5 Pack - Image 1](https://m.media-amazon.com/images/I/91x4cUCT0PL.jpg) ## Questions & Answers **Q: Are these refiillable?** A: No **Q: Does it dry fast?** A: Fairly quickly.
