Filled with Uni-Ball Super Ink, these pens deliver waterproof, fade-resistant, and chemical-proof ink that bonds to paper fibers. Designed for precision and comfort, they offer pressure-sensitive line variation and a leak-proof capped design, perfect for professionals who demand reliability and style in their writing instruments. ## 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. Red Ink in a Box of 12. ## Features - The freedom of a fountain pen without leaking: the unique metal ball of this model moves without friction, no matter what angle the pen is held. - The ballpoint pen is filled with Uni-Ball Super Ink, an advanced ink formula that bonds to the paper fibres. Never fade, waterproof and acid free. - Lower pressure creates a thinner line as the ink is transferred directly over the ball. With stronger pressure, more ink flows around the ball and the line becomes thicker. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B016BHQ450 | | Additional Features | Fade Resistant | | Age Range Description | Adult | | Animal Theme | no animal theme | | Best Sellers Rank | #87,179 in Office Products ( See Top 100 in Office Products ) #1,962 in Gel Ink Rollerball Pens | | Body Shape | Rectangular | | Brand Name | uni-ball | | Closure Type | Click-Off Cap | | Color | red | | Customer Reviews | 4.5 4.5 out of 5 stars (22) | | Drill Point | Fine | | Global Trade Identification Number | 04548351063924 | | Grip Type | Round | | Hand Orientation | Ambidextrous | | Included Components | 12 Stück Rotes Uni-Ball Micro-Air Kugelschreiber | | Ink Base | Water | | Ink Color | Red | | Item Diameter | 8.1 Centimeters | | Item Dimensions | 28 x 81 x 146 millimeters | | Item Type Name | Fountain Pen Tip Air Rollerball Pens | | Line Size | 0.3mm | | Manufacturer | Mitsubishi Pencil | | Material Type | Plastic Metal | | Model Name | UBA-188-M | | Model Number | 190496000 | | Recommended Uses For Product | Writing | | Style | 12 Pack Red | | Unit Count | 12 Pack | | Water Resistance Level | Water Resistant | | Writing Instrument Form | Roller Ball Pen | | Writing Technique | ballpoint | ## Product Details - **Age range (description):** Adult - **Brand:** uni-ball - **Colour:** red - **Ink colour:** Red - **Writing instrument form:** Roller Ball Pen ## Images ![UBA-188-M Fountain Pen Tip 0.5mm Air Rollerball Pens, Red Gel, 12 Pack - Image 1](https://m.media-amazon.com/images/I/81p00uh8IZL.jpg) ## Available Options This product comes in different **Style** options. ## Frequently Bought Together - uni-ball UB-188-Micro Fountain Pen Tip 0.5mm Air Rollerball Pens, Red Gel, 12 Pack - Uni-Ball AIR Micro - 0.5mm Fine Rollerball - Pack of 12 - Black - uni-ball 0.7mm Rollerball Pens --- ## 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.tn/products/253315664-uba-188-m-fountain-pen-tip-0-5mm-air-rollerball](https://www.desertcart.tn/products/253315664-uba-188-m-fountain-pen-tip-0-5mm-air-rollerball) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-16*
