Artline® 579 whiteboard markers contain pigment-based ink that allows for a bolder and more opaque colour payoff. They are able to be used upon any whiteboard or other dry-erase surface to write or draw. Each marker has a chisel tip that outputs pigment based, low-odour and Xylene-free ink and draws 2-5mm lines. These assorted-coloured marker pens have an aluminium barrel that is durable, making for a longer-lasting tool that is a must-have in your home, office or classroom.
