I guess this is an X Metal frame. It's bigger than my Juliets. Serial # is JB005617 which per the OReview belongs to a polished/blue violet combo which this is. The nosebridge is pretty tight, the stem on the left is too, the right side stem folds in but it's not loose. The lenses aren't great but fine for wearing. I wore them to the gym today. They're too big for me so I figured I'd trade them for something I could use more often. If someone really wants to make a cash offer, feel free but I'm interested in trades more at this point. Let me know what you've got. No holbrooks, frogskins, I just don't get those.
