0.4mm feels too fine for the scale you're working at, but a ballpoint smears the moment your sleeve brushes the page. The Artline 235 hits that middle ground. A 0.5mm nib lays down a confident, visible line without the wobble of a broader tip. Acid-free, water-based pigment ink means what you draw stays put — water-resistant, fade-proof, no ghosting on the next layer. The metal ferrule locks into templates and ruling guides so your strokes track true. Drafting, annotation, general writing on the go — this is the pen that doesn't make you check the line twice. Grab one. Stop second-guessing your ink
