Uni-Ball Zento Flow — Jade Turquoise

Ultra-smooth ballpoint gel pen with intense black ink that flows like a dream!

The Flow model features a long metal grip section that adds weight, balance, and elegance — a premium upgrade from the soft grip of the Standard model.

The nib sizes of the Zento series are interchangeable — you can swap a 0.38 refill into a 0.5 pen, and vice versa.
