You need a line that's thicker than a 0.38 but not a full marker. The Artline 210 in purple hits that sweet spot at 0.6mm – bold enough to stand out on a whiteboard printout or a student worksheet, smooth enough that you don't have to press hard to get consistent ink flow. Water-based formula dries the second your pen lifts off the page. No smearing on the next page, no ghosting under a ruler. Just a clean, confident purple line when you need one
