I just bought a Pilot Vanishing Point limited edition 2007 Orange from ebay. It arrived yesterday and the nib unit is the plain gold 18k one and not the 18k Rhodium plated one that should come with these limited editions. The photo on the auction had the pen tilted such that you got a side view of the nib and couldn't see the colour. There was also no mention in the listing that the nib had been swapped.
Now these nib units can be had elsewhere (but for a price) so I'm not too concerned but it's still either ignorance on the part of the seller (a pen shop) or they deliberately tried to fob me off with a replacement nib unit. In any case, I am definitely keeping this pen and I have emailed them to send a replacement nib but I'm sure they won't - they'll probably offer a complete refund. Of course, if they send me a Rh nib, problem solved but I think this unlikely.
Here's my quandary - if they offer a complete refund but I refuse to accept this (I want to keep this pen!!), do I leave bad feedback and annoy them or leave good feedback and forget about it?
