Equipped with Uni’s Super Ink, it offers water, light, and tamper resistance, ensuring your writing stays pristine and secure. This 4-pack includes two black and two blue pens, perfect for professionals seeking precision, durability, and style in their everyday writing tools. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Age range (description) | Adult | | Brand | uni-ball | | Colour | Multicolor | | Ink colour | Black, Blue | | Material | Plastic | | Writing instrument form | Roller Ball Pen | ## Product Details - **Age range (description):** Adult - **Brand:** uni-ball - **Colour:** Multicolor - **Ink colour:** Black, Blue - **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.
