i have a set of like new X Squared Fire Polar lenses for sale or trade. selling because i don't like contrast lenses and would rather have another neutral lens i like. these are basically brand new but they have been mounted and worn for a day to see if i could get used to them. if you are familiar with changing XS lenses it means there is some really small marks on the rim of the lens from mounting in the frame. i can't even get them to show in the pictures and they do not show when the lenses are in the frame. cash wise asking 70 shipped. trade wise i would take ice or ruby. i would add some cash for you if you have any custom cuts or polar custom cuts (pos red, pos red polar, ruby polar, ice polar, deep water blue polar, sapphire polar, ect...) i already have like 3 sets of BIP in my stock so i don't need any more of those.
