You've been there. Carefully ink a technical layout, set the pen down, and watch the line bleed through the template or fade before the project's even handed over. The Artline 234 fixes that. Acid-free, water-based pigment ink sits on the page, not in it. Water-resistant. Fade-proof. No ghosting on your next revision. The metal ferrule grips templates and ruling guides without wobbling, so your 0.4mm lines stay clean from first stroke to last. Whether you're doing architectural detailing, circuit diagrams, or just need a pen that doesn't smudge when someone leans on the desk, this is the one that holds its line. One nib size. One job done right
