You're labelling a stack of DVDs and your regular marker's already smudged, or you need fine text for titles but bolder strokes for section headers without swapping pens mid-task. The Artline 841T handles both from one body. 0.4mm nib for precise titles. 1mm nib for bold labels. Low-odour ink sits in a shared reservoir, so flow stays consistent whether you're on the fine or broad tip. It's built specifically for CDR and DVD surfaces, so it grips the disc without bleeding into the data layer. Black ink. One pen. Two nibs. Sorted
