The Mont Marte Premium Graphic Fineliners 7pc delivers professional precision for artists, graphic designers, and technical illustrators seeking crisp line work. The premium kit contains seven black pens with varied nib sizes ranging from ultra-fine 0.05mm up to a flexible soft brush tip to easily accommodate distinct line weights. Filled with high-quality German ink, these pens provide a lightfast, skip-free flow that resists bleed-through on sketch paper and vellum layouts.
