Uni-ball One P - The Perfect Pocket-Sized Companion
Small in Size, Bold in Expression
Compact Design meets Premium Performance
The Uni-ball One P (Pocket) is a masterpiece of Japanese stationery design. Short, plump, and incredibly cute, this pen is designed to fit perfectly in your hand and your life. Inspired by the smooth, rounded shape of a bar of soap, it offers a surprisingly comfortable grip for its compact size, making it the ultimate everyday carry (EDC) tool.
Key Features:
- Pocket-Friendly Portability: Significantly shorter than the standard Uni-ball One, it clips perfectly into small bags, shirt pockets, or planners without sticking out.
- Low Center of Gravity: Don't let the size fool you. Equipped with a built-in metal stabilizer, the weight is concentrated at the tip for a steady, skip-free writing experience.
- Award-Winning Aesthetics: Winner of the 2023 Good Design Award, featuring a matte finish and a chic, minimalist silhouette that stands out from traditional office pens.
- Signature "One-Ink" Technology: Uses the same revolutionary pigment ink that sits on the paper surface, delivering the deepest blacks and most vibrant colors.
- Functional Wire Clip: The iconic spring-loaded wide-opening clip allows you to attach it securely to thick notebook covers or clothing.
