Up for sale is my carbon x squared with oo bip lenses. Bought this set a while back and really don't need them although I will miss them. They're in perfect condition and have been worn very little. No scratches or marks anywhere, most likely some dust from sitting in my case. These are super hard to find. Comes with everything but extra rubber. Asking $540 obro shipped within the United States. International shipping will be on the buyer.
