This is a fun pen. A demonstrator with a Parker 51-style hooded nib and a piston filling mechanism. A lot of clear pens tend to suffer from barrel cracking, but this one has been doing well for several years. It writes well, holds a lot of ink, and there is no leaking or evaporation.
This is a good budget pen with the best price-to-quality ratio of any pen that I have. You can’t tell from my picture but the cap posts, so you don’t need to worry about losing it while you’re writing.
