Wow, good lookin' pens! I'd be interested in some general info as well.
As far as selling them here goes, my gut tells me that you wouldn't really be able to post about them. You could always offer them to someone in full/partial trade, but since you make them yourself, I'd say it falls under a combination of the "No services" and "dealers" rules (imho) and hence wouldn't be allowed as a FS/T post. So long as people "know" that you're the pen person, we can shuffle potential business your way via PM/email and nothing (to my knowledge) is keeping you from contacting folks that you hear might be interested.
