I just bought these on ebay for 475.00 so I will let them go for that price. I'm open to offers. No serial number on these. Comes with glasses, xmetal case, and cloth. These look great in my opinion. They're loose but definitely doesn't affect wearability. There's a minor blemish on one of the lenses but not that noticeable. The color is very good with no noticed discoloration. Pics below.
