Hi, Just wondering how to tell if your frogskin lx is authentic. The ones i bought (Frogskins LX Matte Black w/Ruby Iridium) came in a black box with a warranty paper, a newsletter paper, had a barcode sticker on it, and came in a microfiber bag. Also the serial number on the left arm seems to match with the color and type. Just a bit worried because the left metal hinge seems a little loose compared to the right one and the 'O' on the right arm is slightly sticking out and it seems like a little loose too. I don't know just seems a little fishy now after inspecting it closer and feeling a little paranoid. Couldn't really find much info on the LX so I hope you guys can help thanks!
