I have this XX 24K in pretty good shape. Its 4th or 5th gen, whichever had no markings. (I'm a Juliet guy so I don't know XXs like that) I also have an extra set of lenses for them. They don't look like they've been used, but I can't say for sure. The plasma orbitals look perfect. The gold parts have some slight discoloration. Not too bad. The nose bridge is not in need of a tune but the right side is a bit more flexible than the left. The ear socks slide a bit but I imagine they could be cleaned. One of the nose bombs is missing but I heard Juliet ones will work. The lenses are very good. There are a couple of pin pricks on the right lens but they would barely show up in pictures. The left has nothing I can see. Lets assume they have cleaning swirls. I tried to take the best possible pictures. If any more are needed, I can take them. Ideally I'd like another XX in trade. Black on black. It would have to have a matching serial box. Condition of frame is negotiable and lenses even more so. I'd be ok having to have lenses cut. The matching serial box is the only deal breaker. I'm always open to hearing offers. I mainly collect X Metals but something O Matter may catch my eye. It never hurts to try.
