hey guys decided to join, ive had about 8 pairs of oakleys in the past and lets say my most expensive pair I bought were my X-Squared they are the polished frame on polarized vr28 lenses. got them on ebay about 4 years ago new for 395$ since that day I stopped wearing my other glasses. in fact I don't think ill ever wear another plastic frame again. I wear these on my boat, to Disneyland yes on the rides too, riding my road bike everywhere. they do have a serial number on them. and I have the coin and og box. my next pair will be the 24k x squared
