Review: muy malo ## 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 0.7mm ball delivers a line width of between 0.35mm and 0.55mm (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 pack contains six pens. All with black ink. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MA6JEF8 | | Additional Features | Rollerball | | Age Range Description | All Ages | | Animal Theme | no animal theme | | Best Sellers Rank | #68,833 in Office Products ( See Top 100 in Office Products ) #520 in Liquid Ink Rollerball Pens | | Body Shape | Round | | Brand Name | uni-ball | | Closure Type | Click-Off Cap | | Color | Black | | Customer Reviews | 4.5 4.5 out of 5 stars (929) | | Drill Point | Medium | | Global Trade Identification Number | 05056225281477 | | Grip Type | Smooth | | Hand Orientation | Ambidextrous | | Included Components | 6 pens | | Ink Base | Water | | Ink Color | Black | | Item Diameter | 0.7 Millimeters | | Item Dimensions | 8 x 12 x 1 centimeters | | Item Weight | 0.11 Pounds | | Line Size | 0.35-0.55 Millimeters | | Manufacturer | uni-ball | | Material Type | Metal | | Model Name | Air | | Model Number | UBA-188-L | | Recommended Uses For Product | Calligraphy | | Style | Sensitive | | Theme | People | | Unit Count | 6.0 Count | | Writing Instrument Form | Roller Ball Pen | ## Product Details - **Age range (description):** All Ages - **Brand:** uni-ball - **Colour:** Black - **Ink colour:** Black - **Writing instrument form:** Roller Ball Pen ## Images ![Uni-Ball AIR - 0.7mm Medium Rollerball - 6 Pack - Black - UBA-188-L - Image 1](https://m.media-amazon.com/images/I/71PbFgnk+zL.jpg) ![Uni-Ball AIR - 0.7mm Medium Rollerball - 6 Pack - Black - UBA-188-L - Image 2](https://m.media-amazon.com/images/I/61rkvJ1XjjL.jpg) ![Uni-Ball AIR - 0.7mm Medium Rollerball - 6 Pack - Black - UBA-188-L - Image 3](https://m.media-amazon.com/images/I/71gPMfeNivL.jpg) ![Uni-Ball AIR - 0.7mm Medium Rollerball - 6 Pack - Black - UBA-188-L - Image 4](https://m.media-amazon.com/images/I/615b3xtX6vL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by Q***? on 15 December 2024* Ce sont mes stylo préférés..j'ai une belle écriture avec... ### ⭐ Review *by A***S on 26 August 2025* muy malo ### ⭐⭐⭐⭐⭐ Review *by A***R on 29 September 2025* I bought these for my daughter for school. She loves them. They write really well, and are not too thick. The ink flows really well. They are a lovely pen to write with. I only bought black so I cannot comment on the colour range available. ## Frequently Bought Together - Uni-Ball AIR - 0.7mm Medium Rollerball - 6 Pack - Black - UBA-188-L - Uni-Ball AIR - 0.7mm Medium Rollerball - 6 Pack - Blue - UBA-188-L - uni-ball Air - 0.7mm Medium Rollerball - 3 Pack - Red - Uba-188-L --- ## 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.pe/products/278339898-uni-ball-air-0-7mm-medium-rollerball-6-pack-black](https://www.desertcart.pe/products/278339898-uni-ball-air-0-7mm-medium-rollerball-6-pack-black) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-06-26*
