Hello forum, I've just bought what I think may be a Platinum PKA 500. The design is white with green clovers, exactly the same as the pen in this link http://www.vitstyle.com/home/601-platinum-18k-gold-sf-nib-pocket-fountain-pen.html with one difference being, the nib is steel. I checked the photos very well, above the P symbol on the nib, nothing is written. Only some japanese under it. Does anybody have any expeirence with the performance of this pen/nib? And would it be possible to swab the nibs on it? I intended this pen to be a present for my wife but was hoping the nib would be gold. Unfortunately, it wasn't. The pen is still on its way in the mail.
