Zento Low-Friction Rollerballs are the latest & greatest office pens from Uniball. These super-smooth writers don't skip, scratch, or hard-start, but they're still very quick drying and they work on all kinds of surfaces. Cheap paper, triplicate forms, and textured sketch paper will all take Zento marks just fine.

Zento Flow is an upgraded version of the regular Zento pens, featuring a cool anodized aluminum grip that adds weight and style to the pen. The refills are interchangeable with those used in the original Zento pens.

0.5 mm; black ink. Refillable with Uni Zento cartridges. Made in Japan.
