Hello all! I have a vexing question. How do people trade pens over the internet? I bought a clear Pilot Custom Heritage 92 with a Fine nib from a reputable ebay seller in Japan. However, I'm now over my love affair with clear demonstrators and badly want to get a colored version of the C92 with a Medium nib. I've never seen a smoke or blue colored C92 on classifieds within the $135 I paid for mine and I haven't been able to snipe a C74/C91 off of ebay (*to change the medium nib) without enough margin to break even when I inevitably sell off the other pen. So comes the conundrum If I can't sell and buy, how do I trade my pen for one that I want? Post a wanted ad in the classifieds and hope? When I buy a pen from a member, I have a chance to recoup my loss via Paypal if things go south. How do total strangers establish enough trust to send each other pens through the mail? Any suggestions? I know this is a slightly dumb question to ask but I think others might be wondering the same thing...
