Mitsubishi Pencil Uni-ball One Gel Ballpoint Pen 0.38mm – Set of 8 Vibrant Colors

Upgrade your everyday writing with the Mitsubishi Pencil Uni-ball One Gel Ballpoint Pen 0.38mm – Set of 8 Vibrant Colors.

Uni-ball One uses a specially developed pigment gel ink with larger “beads-pack” particles that stay closer to the paper surface instead of soaking in. This makes black ink darker and colors more vivid and crisp, while still drying quickly and resisting smudging—ideal for right-handers and left-handers alike. 

This set includes 8 practical yet vibrant colors:

Black, Blue, Blue Black, Sky Blue, Green, Orange, Red, and Pink. 

They’re perfect for color-coded notes, headings, underlines, and creative accents in your planner or study notebook.

The 0.38mm fine tip produces precise, clean lines that are great for small handwriting, Hobonichi-style planners, and detailed annotations.  Each pen has a simple white barrel with a comfortable grip and a wide-opening wire clip that easily attaches to notebooks and pen loops. 

Whether you’re a student, professional, or stationery lover, this Uni-ball One 8-color set brings high-contrast, highly readable notes and a smooth writing feel to your everyday carry.
