Mitsubishi Uni-ball ZENTO Refills

Because a good pen deserves a second act. These Uni-ball ZENTO refills are designed specifically for the ZENTO pen, delivering the same smooth, controlled writing experience without forcing you to abandon a pen you’ve grown rather attached to. Available in 0.38mm for neat, precise notes or 0.5mm for a slightly freer flow, each refill slots in effortlessly and gets straight back to work. Sensible, satisfying, and quietly reassuring – exactly what a refill should be.
