Quite fun, almost feels like calligraphy. ## 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. - This set contains four blue inked pens, one of each of the following barrel colours: Pink, Orange, Green and Light Blue. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09Q8ZLVKP | | Additional Features | Liquid Ink | | Age Range Description | Adult | | Best Sellers Rank | #108,937 in Office Products ( See Top 100 in Office Products ) #308 in Liquid Ink Rollerball Pens | | Body Shape | Round | | Brand Name | Uni-Ball | | Closure Type | Click-Off Cap | | Color | Blue,Green,Orange,Pink | | Customer Reviews | 4.4 4.4 out of 5 stars (63) | | Drill Point | fine,micro | | Grip Type | Ribbed | | Hand Orientation | Ambidextrous | | Ink Base | Water | | Ink Color | Blue | | Item Dimensions | 5.51 x 2.36 x 0.39 inches | | Line Size | 0.3 Millimeters | | Manufacturer | Mitsubishi Pencil Co Ltd | | Material Type | Metal | | Model Name | UBA-188-M | | Model Number | UBA-188-M | | Recommended Uses For Product | Writing | | Style | Stick | | Theme | Rainbow | | Unit Count | 4.0 Count | | Water Resistance Level | Water Resistant | | Writing Instrument Form | Roller Ball Pen | ## Product Details - **Age Range (Description):** Adult - **Brand:** Uni-Ball - **Color:** Blue,Green,Orange,Pink - **Ink Color:** Blue - **Writing Instrument Form:** Roller Ball Pen ## Images ![AIR Micro - 0.5mm Fine Rollerball - Blue Ink - [Pack of 4] - Pink, Orange, Green and Light Blue Barrels - Image 1](https://m.media-amazon.com/images/I/71Ks-5UXf0L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice Pen. *by N***M on March 11, 2026* Extremely smooth writing. Drying time isn’t too long, but the ink definitely smears. ### ⭐⭐⭐⭐⭐ Great pen! *by R***L on August 27, 2025* Flowiest pen of all pens! Quite fun, almost feels like calligraphy. ### ⭐⭐⭐⭐ All write the same blue ink despite being multi-colored. *by S***E on March 11, 2026* I gave these 4 stars because they all write in the same blue ink vs the color of each pen. I found that to be confusing and pointless. I did not realize they had "blue ink" advertised on them until after I opened the pack. Had i noticed earlier, I would not have purchased these. Overall, I love how they feel while writing, light weight with smooth smear proof results. The pack was slightly expensive but it is ok. ## Frequently Bought Together - uni-ball AIR Micro - 0.5mm Fine Rollerball - Blue Ink - [Pack of 4] - Pink, Orange, Green and Light Blue Barrels - Uniball Air Micro Pen, Set of 4 - Black (UBA 188 M) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/450088018-air-micro-0-5mm-fine-rollerball-blue-ink-pack-4](https://www.desertcart.kr/products/450088018-air-micro-0-5mm-fine-rollerball-blue-ink-pack-4) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-11*
