Body Color: Sugar Brown

The uni-ball one 3 3-Color Gel Ink Pen by uni Mitsubishi Pencil combines the signature deep ink of the uni-ball one series with a rotating retractable mechanism for three colors in one compact pen. The short, rounded barrel delivers an endearing form while maintaining comfortable writing through a stabilizer mechanism that optimizes the center of gravity. M

The uni-ball one ink technology suppresses ink penetration into paper fibers for deep blacks and vivid color development. Lines appear sharp and assertive on notebooks and planners, maintaining clarity without show-through. The rotating mechanism allows quick color switching between black, red, and blue while the short barrel design fits easily into pockets and pen cases.
