Retractable emulsion pens combine oil, water and pigment to deliver the smoothest writing experience. An effortless glide ensures a remarkable writing performance with every stroke of the pen. Ink is quick-drying and smear-resistant while maintaining brilliant and bold writing. Engraved emulsion emblem on the barrel and the metal accents of the plunger and tip offer a sleek appearance. Stylish, sophisticated, Z-Mulsion EX pens with fashion-forward accents also offer a comfort grip and the popular 1.0mm point size for a bold, streak-free write-out. The color of the rim around the plunger indicates ink color. Pens are refillable with Zebra EQ-Refills.
