Most of the pens advertised as 6359s on eBay are not. Here are specific flavors of four other AL-Star clones I own. All are XF,
The metal one sodul mentioned. Mine is a bit toothy but I like it. However, I don't know how to get another. Like sodul, I ordered a 6359 and got this.
The Yiren 312C which is not usually sold as a 6359 but rather as a "568" with no brand. I have three of these and like them all. Mine have open nibs, The finish looks metallic but I think it is plastic. Two flats, "Yiren" on the barrel, "359C" on sticker on cap, chrome clip, clear section, black feed, "+" on finial. Sold by hejing1314 with whom I have had generally good experiences. 99 cents US. This would be my top choice unless you have some way to ensure you get a real 6359.
A pen that looks like a Yiren 359C but with no Yiren markings and a smoke section. $1.39. I have two. One is really nice; the other has more tooth than I would like. $1.39, Sold as a 6359 and I don't know how you would tell in advance if you will get one of these instead so I would go with the Yiren.
A pen that looks like the one above but has a black clip, nothing on the finial, gunmetal nib, and section color matching body. One of mine is a slightly metallic dark teal and the other is flat black. These are the only colors available and are quite distinctive. The teal pen writes very well; the black one has barely adequate flow with Hero carbon Black ink (which is known to be balky). Search for

$1.65 from laonan123, a reasonable seller. The seller does not advertise it as a 6359 so you can be reasonably confident you will get one of these rather than a random fake. The photos on eBay are quite accurate as to what these look like and you may like their looks.
