Hi everyone. I'm not entirely sure what series these are. I bought them new in 2005 from an Oakley dealer. I remember they were titanium. The frames are titanium. I think they may be Juliet 15s, but I can't find a serial number to confirm that. The only marking I can find is on the rubber inserts which have "15." I know they are authentic, as I bought them at an Oakley dealer, but somewhere over the last 10 years I lost the box. Any help would be great! I'm trying to get them tightened. The nose piece has become so loose that they are unwearable.
