This is a Montblanc mechanical pencil. It's the discontinued S-Line, black in color, with a 0.5mm lead. It has a W-Germany engraving, suggesting it was made during the West Germany era. The S-Line is slimmer than current Montblanc models. It features the white star at the tip of the clip. It has been stored unused, but as it was kept at home, I'm listing it under the "Like New" category. Also, I removed a broken piece of lead inside the pen, so I have handled it. Please consider it!
