[Limited] Mitsubishi Uni-ball One CITY POP - Sunny Day Blue - 0.5mm

- Unlike general gel inks, the newly developed "UNI-BALL ONE" ink uses a new pigment that minimizes the penetration of colorants into paper fibers.
- The blacks are darker, the colors are more vivid, and you can write crisp characters that are easy to remember.  
- No bleeding, fast-drying ink.
- Stylish design.
- The oval-shaped "Open Wire Clip" is a movable clip that is easy to insert into a notebook or diary, which is very functional.
