I sell vintage pens in S.Korea. All pens have undergone a thorough inspection, so you can use them with confidence. Personally, I like Parker fountain pens, especially all models of the Parker 51 and the late-model converter type of the Parker 61 Mk II. A moderately broken-in 51 with an EF (Extra Fine) nib is truly movingly smooth. You'd need something like a Pelikan or Montblanc with an M (Medium) nib to even come close to that level of smoothness. And these are pens purely for writing, with absolutely zero intention for showing off or display to others. I don't know what kind of pens will come out in the future, but I doubt if products like these will ever be produced again. Let's cherish and use our vintage pens carefully~!!
