I just bought a pair of Flying Tiger Gascans from ebay. They are in very good shape, not a single scratch as far as I can tell. The only problem I have is that the earstems feels loose when in the open position, compared to my 2 year old Gascan which I got brand new. Is this an easy fix? Or if I send it for repairs, any ideas how much that would cost? Thanks Bonus Question: Anyone know if the lenses on these are polarized? It does not have the etching on it, bit I'm not sure if they even do etching for special edition stuff.
