Uniball One Gel Pen (0.38mm)

The Uni-ball One gel pen series is a multi-award-winning collection that has redefined ink technology with its proprietary "One Ink" formula. Unlike traditional gel pens where the ink pigment absorbs into the paper fibers, Uni-ball One uses large-particle pigments that sit directly on the surface. This results in the darkest blacks and most vivid colors possible, creating high-contrast writing that is clinically proven to be easier to remember. The ink is also exceptionally fast-drying and smudge-resistant, making it a reliable choice for left-handed writers and detailed planners who need clean, sharp lines every time.

Beyond its superior ink, the series is known for its iconic minimalist design and functional innovation. Each pen is equipped with a unique, spring-loaded wire clip that opens wide, allowing it to secure firmly onto thick notebook covers or clothing. 

8-Color Set: Cappuccino Brown, Mango Orange, Avocado Green, Nemophila Blue, Poppy Red, Plum Purple, Sesame Grey, and Black
