looking for unique pen

[ronz91]

This pen was given to me by a friend. She does not know where she got it. It seems to be some kind of modern fountain pen as it does not have a ball point (see pic). The pen has 4 metal pieces that run up the side to form the point. The 'Plendil' brand on it seems to be a pharmeceutical company. So I suspect it may be one of those pens pharmeceutical sales reps give to their customers. Possibly a generic pen that you order with your branding on it as it doesn't look or feel very expensive.

Anyone know where I can buy more of these?
