A compact gel pen with elevated contrast and a satisfying click, Uni-ball One P delivers crisp, easy-to-read writing in a short, wide form that’s comfortable to hold. Its pigment-based black ink sits on the surface of the page for darker blacks and cleaner lines—fast drying and bleed resistant to keep notes clean.
The clear, chunky barrel offers a minimal, modern look with a balanced feel in hand, while the wide-opening wire clip secures to planners and notebooks with ease. A 0.5 mm tip provides controlled detail for daily planning and precise markups.
