I have contacted the seller of what looks like a plasma (OR possibly polished) romeo 2. It appears to have OEM BIP lenses in the frame.. I asked if they were oem, and if so when were they changed. I was told they are the original lenses and they were that way when bought from a duty free shop a few years back? i didn't think plasma or frame any other than x metal came with BIP lenses.. is it likely that they had been changed by the shop for some reason? or did some frame sell with this combo? Thanks
