i have for sale a pair of 24k XX Metal. Second Gen. They are in great condition with non of the normal flaking or fading of the gold. The only bit that has worn is behind one of the intake ports, as can be seen in the pics. Slightly more play in one orbital than the other but a long way from needing a tune-up. I would rate the lenses 8/10 as they have one small scratch and a few cleaning marks on the inside that can only be seen when holding up to a light source. All rubber is good - nose bombs are proper XX and not stretched Juliet! I will include an X Metal Ballistic case and micro fibre bag. I am asking for £300/$480 + shipping. This will be £7 UK/ $20 to US. For other destinations please ask for a price. Payment by paypal f&f or add the fees.
