Uni-Ball One features a newly developed gel ink and a simple shaft design. The new Uni-Ball One has a deeper black color and a more vibrant color than typical gel inks, and can create impressive notes that will look sharper when you look back later. General quick-drying ink achieves quick-drying by increasing the penetration of the ink into the paper. As a result, ink bleeding or strike-through sometimes occurred. The newly developed "Uni-Ball One Ink" enables the liquid component to quickly penetrate into the paper by changing the ratio of the solid and liquid components in the ink, while allowing the solid color material to remain on the paper. Although it is a quick-drying ink that penetrates the paper quickly, it does not bleed or strike through to prevent the color material from being absorbed into the paper. The shaft design is simple and straight. The color ink uses an off-white axis color that blends into the living space, resulting in a calm impression. The oval-shaped "open wire clip" has a stylish design and is a movable clip that can be easily inserted between notebooks and notebooks. Review: Favorite pen - Great quality set of pen. Looks expensive and nice to use. Best to use on hobonichi paper, it doesn’t bleed through pages. Review: Smooth - Thin but doesn’t skip. It’s a hard combo to find. Good for small calendar spaces but I wouldn’t write long pages with them. ## Features - New Uni-Ball One Ink Adopted - Ballpoint Diameter : 0. 38mm - 8 Colors Set : Black, Blue, Sky Blue, Green, Orange, Red, Pink, Blue Black ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0851Y8TJL | | Additional Features | Pocket Clip | | Age Range Description | Adult | Children | Teens | | Age range (description) | Adult | Children | Teens | | Animal Theme | no animal theme | | Best Sellers Rank | #17,132 in Office Products ( See Top 100 in Office Products ) #369 in Gel Ink Rollerball Pens | | Body Shape | Rectangular | | Brand | 三菱鉛筆 | | Brand Name | 三菱鉛筆 | | Closure Type | Retractable | | Color | Black,Blue,Sky Blue, Green, Orange, Red, Pink, Blue Black | | Colour | Black,Blue,Sky Blue, Green, Orange, Red, Pink, Blue Black | | Customer Reviews | 4.5 out of 5 stars 2,949 Reviews | | Drill Point | ballpoint | | Global Trade Identification Number | 04902778261439 | | Grip Type | Smooth | | Hand Orientation | Ambidextrous | | Included Components | 8 pens | | Ink Base | Water | | Ink Color | Multicolor | | Ink colour | Multicolor | | Item Diameter | 10 Millimeters | | Item Dimensions | 14 x 9 x 2 centimeters | | Item Type Name | Gel Ink Ballpoint Pen | | Line Size | 0.38 millimeter | | Manufacturer | Uni | | Material | Stainless Steel | | Material Type | Stainless Steel | | Model Name | UMNS388C | | Model Number | UMNS388C | | Recommended Uses For Product | Coloring, Writing | | Style | simple | | Theme | Rainbow | | Unit Count | 8 Count | | Water Resistance Level | Not Water Resistant | | Writing Instrument Form | Roller Ball Pen | | Writing Technique | ink gel | | Writing instrument form | Roller Ball Pen | ## Product Details - **Age range (description):** Adult | Children | Teens - **Brand:** 三菱鉛筆 - **Colour:** Black,Blue,Sky Blue, Green, Orange, Red, Pink, Blue Black - **Ink colour:** Multicolor - **Writing instrument form:** Roller Ball Pen ## Images ![Uni Uni-Ball One, Gel Ink 0.38mm Ballpoint Pen, 8 Colors Set (UMNS388C) - Image 1](https://m.media-amazon.com/images/I/61LcLR97TxL.jpg) ## Questions & Answers **Q: do you also sell ink refills for these pens? I'm looking for blue** A: These pens do not write well at all. **Q: How do these compare to Tül pens?** A: Well TUL has a larger ball base than the UNI. I find a thinner base more functional **Q: Does the ink show up on black paper or is it just for white paper?** A: Just for white, I have been looking for a milky equivalent. I keep hoping they will make some :) since these are my favorite. **Q: Is the ink archival and waterproof?** A: As far as I can tell yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Favorite pen *by M***E on 27 December 2023* Great quality set of pen.
