Greetings all, I just recently received my first pair of gen 2 matte red frogskins. I am trying to deduce authenticity and am having a tough time, so I'm using one of my life-lines and polling the experts here... They appear legit as everything else looks right and other frogskins replacement lenses have fit perfectly in the frame, but my question is... Does the matte red pair have a sku on the inside earstem? Thank you for your help guys!
