I bought mine this month from www.isellpens.com (in Arizona, USA) for about $5 USD. The whole order (more pens and three bottles of ink) was over $100, which made shipping free. Service, including several quick answers by Todd Nussbaum to my e-mails, was excellent. This replaces a pen almost exactly like it which I got, used and lost in China in the late 1980's. It made writing Chinese easier, and I saw people everywhere using it. I was disappointed to find out recently that ballpoint and gel rollerball pens took over in China in the 1990's.
The Hero 329 is an imitation of the Parker 51 or 21 designs (the clip's shape isn't like an arrow; thanks, Johan, for the distinction). The barrel and section are streamlined and all in one color, the section cover also being a hood over almost all of the nib. The barrel and section cover are plastic (green on mine). The cap is uncolored metal, streamlined like the rest of the pen, fitting snugly with neither threading nor snap. The clip can grip any reasonable thickness of fabric, including coat fabric. The brand name is engraved on it in Chinese, along with "329." The cap also says "FINE LINE," in English and Chinese, in black lettering.
This pen is comfortable to hold whether the cap is posted or not. The cap posts securely on the end of the barrel.
The nib is steel, fine and firm.
The permanent reservoir (bottled ink only, yeah!) is a true "aerometric" squeeze-fill design with a tube partway up the middle of the sac. The sac is clear, functioning as an ink level window. The reservoir continues downstream from the sac, in clear plastic which functions as a second ink level window and as the thread support for the barrel; loosening the barrel a few turns from the section uncovers that window.
I filled this pen with Levenger Gemstone Green ink. I've used it to write on lined pad paper, lightweight cotton paper stationery, inkjet paper and laserjet paper. Like any good fountain pen, the Hero 329 needs almost no pressure on the paper for writing. Although writing with it makes scratching sounds, the feeling is only slightly scratchy, and the nib has not snagged up any fibers. The line width and amount of ink deposited are easy to control.
The nib, like any fine nib, might be too fine for children who are just learning how to write.
Other than that, this is a great pen for anyone else I can think of, and the price is right. Enjoy!
