It is Harder to tell for the X-metal line (Romeos,[url="http://nikefree50leopard778.tumblr.com"]nike free 5.0 leopard[/url], Juliets,[url="http://celinetriobag873.tumblr.com"]celine triobag[/url],jeremy scott adidas wings, Pennys),womens nike free run 3 hot punch,[url="http://nikefree30review362.tumblr.com"]nike free 3.0 review[/url], by just looking at them. The X-metals never have a logo on the bridge of the nose. If you see this, you are looking at a pair of fake Oakley sunglasses. Additionally check for where screws/rivets go. All of the X-metals have rivets that hold the frame together on the bottom of the lens frame and ones that keep the bridge connected to the frames. If there are no screws/rivets, you are looking at fake oakley frames. There are really good copys of Romeos and Juliets that are plastic,[url="http://mcmdufflebag522.tumblr.com"]mcm dufflebag[/url],, and have no rivets. Also, real Oakleys of this style come in plain metallic colors; that is to say they aren't made in yellow,[url="http://tiffanyblue139.tumblr.com/"]nike free 3.0 v4 womens[/url], blue,[url="http://celineonlinestore628.tumblr.com"]celine online store[/url], green or red. Real X-metals are never painted. Anything other than a dull smoke or silver metal color is most likely a fake. Sometimes you can find horrible copys made of the metal Oakley frames. These are very cheap and look like they are made of some kind of sheet metal. Again, look for rivets. If they look glued together,[url="http://adidasjeremyscott622.tumblr.com"]adidas jeremy scott[/url],you are spotting fake Oakley sunglasses.
