The Zento is the latest release from Uni, featuring a new gel ink designed to emphasize smoothness and cushion when writing, while resisting bleedthrough and feathering. Zento ink has a matte finish and dries quickly. The Zento Flow features a smooth metal barrel that some might find more durable than the basic Zento model.

All Zento Flow pens contain black ink in either .38mm or .5mm tip sizes. Blue and red refills are available for purchase separately.

Made in Japan.
