Designed with a curved and ergonomic barrel, the Artline® Antimicrobial whiteboard marker pens are comfortable to write with and designed to fit neatly into your hand. They feature 1.5 mm nibs that are able to produce bold lines so that messages can be read easily even from a distance. The ink has a low odour for non-invasive smell, and is alcohol-based and pigment-based for more opaque colour payoffs. With their uniform black ink colour and other features, the Artline® Supreme whiteboard markers are perfect for use in classroom or office environments.
