Uniball Zento Refill 0.5mm

This refill cartridge (sold individually) is designed exclusively for Uni Zento Rollerballs, the latest and greatest ink technology from Mitsubishi. 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.

0.5 mm. Refill only — pen body not included. Made in Japan.
