T Serialized. Microbag only $300 shipped worldwide FF or 4.4% PayPal. I believe this pair's a 1st gen Titanium; boney in color. Frame does not need tuning as per my opinion, but definitely not as tight as new Lens still has much life to it. A dot or so on the left lens, I'd rate a conservative 8/10. Left arm has a few dirts & dots as per picture. the norm for titanium.
