Swap the refill, keep the pen
The ink is the secret
A collector's item
Uni-ball One P
The pocket edition One pen: short and chunky with a weighted tip — playful, palm-sized, and winner of the Design Award at the 2024 Japanese Stationery Awards.
Smooth plastic finish, without soft grip.
Uni-ball One F
The grown-up upgrade to the original One: a wider barrel with a weighted metal tip and low center of gravity, built for long writing sessions.
Smooth plastic finish, without soft grip.
Uni-ball Zento Standard
The everyday Zento: a softly colored barrel with a long, cushioned rubber grip that stays comfortable through longer journal sessions.
Uni-ball Zento Flow
The Zento Standard's two-tone upgrade: the rubber grip swapped for a long metal section that adds weight, balance and a touch of elegance.
Uni-ball One
The original of the family: a light, slim, minimalist white body — and the only model who comes pre-packaged with fun ink colors, from pastels to moody almost-blacks. Those refills swap right into the other pens, should you wish.
Smooth plastic finish, with soft grip.
