I have a set of used Kahles 10x42 binoculars that I don't need. The lenses are scratched, I've included some pics to show this. Never could keep from losing the lens covers until I realized that butler creek flip-ups work great but the deed was already done. At any rate, I don't believe they affect the performance. Included with the binocs: kahles neoprene strap butler creek flip-up caps for the objectives winged set of eye cups flat set of eye caps all paper work with original box Asking $350 If you buy them, receive them, don't like them, just return them and I'll send your money back.
