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
If you buy them, receive them, don't like them, just return them and I'll send your money back.
