Rotring 600 pens have a special place in the hearts of anyone who loves modern design. Rugged steel beauties, these pens are all about hard work. Our preowned pen looks almost brand new with very little wear. The tail-click action works well. This one comes with a working black ballpoint refill. Another nice thing about these pens is that they take very easy-to-find Parker-style refills. No obscure German refills for this pen. 13.8cm
