Ink Color
The Uni-ball One Gel Pen Refill by uni Mitsubishi Pencil is designed for use with the Uni-ball One 3 multi-color pen body, letting you customize your color lineup. It delivers dark blacks and vivid colors through uni-ball one ink technology that suppresses color material penetration into paper fibers. The result is writing that stands out clearly on your notebook or planner pages. These refills are also compatible and interchangeable with STYLE FIT refills.

Note: Sharp refill (model number: M5R-189) cannot be used because it cannot be knocked. You can write with STYLE FIT refills, but the ring color display cannot be changed.
