Encased in acetal plastic, the metal ball ensures smooth ink flow, while Uni’s Super Ink offers water, light, and tamper resistance for secure, professional writing. This set includes two black and two blue pens, designed for ambidextrous use and crafted in Japan by Mitsubishi Pencil Co Ltd. ## Description 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. This set contains four gel ink rollerball pens, two with black and two with blue ink. Review: Perfect Fountain Pen Imitator - I had to write with a fountain pen for a specific piece, and love my micro ball pen but it didn’t have the right flow to match a fountain pen. When I did purchase one, it just didn’t quite feel right, and so I found these. The pen is very similar to other uniball offerings in shape, and hold. Glides across the paper even more than my microball which took some adjust along with the slower drying ink, but the overall quality was sublime. Compared to a fountain pen you can’t tell the difference unless someone was watching you write with it, and considering it is a fraction of the cost and doesn’t have the problems to go with it, it’s a no-brainer. Review: Don't come in the uniball paper packaging - I was skeptical as they didn't arrive in the uniball paper packaging. But once they were opened and used, they were fantastic. ## 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 pens, two with black and two with blue ink. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B59W6ZPB | | Age Range Description | Adult | | Age range (description) | Adult | | Best Sellers Rank | 53,057 in Stationery & Office Supplies ( See Top 100 in Stationery & Office Supplies ) 178 in Liquid Ink Rollerball Pens | | Body Shape | Stick | | Brand | uni-ball | | Brand Name | uni-ball | | Closure Type | Click-Off Cap | | Colour | Multicolor | | Country Of Origin | Japan | | Customer Reviews | 4.6 out of 5 stars 18 Reviews | | Drill Point | Fine | | Included Components | Four pens | | Ink Base | Water | | Ink Colour | Assorted | | Ink colour | Assorted | | Is the Product Left or Right Handed? | Ambidextrous | | Item Dimensions | 14 x 5.2 x 1.6 centimetres | | Item Weight | 0.04 Kilograms | | Line Size | 0_5mm | | Manufacturer | Mitsubishi Pencil Co Ltd | | Material | Plastic | | Material Type | Plastic | | Model Name | Uni-Ball AIR Micro | | Recommended Uses For Product | Writing | | Special Features | Pressure Sensitive | | Style | Stick | | Unit Count | 4.0 count | | Water Resistance Level | Water Resistant | | Writing Instrument Form | Roller Ball Pen | | Writing Technique | rollerball | | Writing instrument form | Roller Ball Pen | ## Product Details - **Age range (description):** Adult - **Brand:** uni-ball - **Colour:** Multicolor - **Ink colour:** Assorted - **Material:** Plastic - **Model name:** Uni-Ball AIR Micro - **Point type:** Fine - **Special feature:** Pressure Sensitive - **Unit count:** 4.0 count - **Writing instrument form:** Roller Ball Pen ## Images ![uni-ball AIR Micro - 0.5mm Fine Rollerball - 4 Pack - Black and Blue Ink - UBA-188-M - Image 1](https://m.media-amazon.com/images/I/711ptX0E5rL.jpg) ![uni-ball AIR Micro - 0.5mm Fine Rollerball - 4 Pack - Black and Blue Ink - UBA-188-M - Image 2](https://m.media-amazon.com/images/I/61ITnJTiFsL.jpg) ![uni-ball AIR Micro - 0.5mm Fine Rollerball - 4 Pack - Black and Blue Ink - UBA-188-M - Image 3](https://m.media-amazon.com/images/I/61hBDkoObPL.jpg) ![uni-ball AIR Micro - 0.5mm Fine Rollerball - 4 Pack - Black and Blue Ink - UBA-188-M - Image 4](https://m.media-amazon.com/images/I/61ixfyRI8+L.jpg) ![uni-ball AIR Micro - 0.5mm Fine Rollerball - 4 Pack - Black and Blue Ink - UBA-188-M - Image 5](https://m.media-amazon.com/images/I/61wNMXjqs2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect Fountain Pen Imitator *by J***E on 21 December 2024* I had to write with a fountain pen for a specific piece, and love my micro ball pen but it didn’t have the right flow to match a fountain pen.
