You know the one. The marker that ghosts, smudges, or dries out halfway through a staff meeting. The Artline 509A fixes that. The 5mm chisel nib lays down bold, dense red lines that wipe clean in a single pass on enamel, porcelain, or melamine boards. No residue. No ghosting. The alcohol-based pigment ink keeps colour vivid even after a long training session, and the low-odour formula means nobody's coughing through a 40-minute huddle. Stop reaching for that dried-out stick. Add to cart and have a marker that actually works on your board
