Need a black marker that actually wipes clean and doesn't make your hand cramp after two pages of notes? This Artline Supreme does the job. The ink goes down crisp and even on traditional glass boards, electronic whiteboards, and lap boards. The glossy grip means it sits naturally in your hand whether you're running a classroom or scribbling a to-do list on the kitchen board. Part of the 10-colour Supreme range, so when you need red for the urgent stuff or blue for the planning column, it's all in the same family
