A classic and hard to find pair of Oakley sunglasses, these lenses are getting very difficult to find brand new.  If you want a refresh on your Mumbo M frames, buy while you can.  These simply don't last long.

You will receive one lightly used genuine replacement lens for the original Mumbo frames only.  I have tested these in Mumbo frames, but they do not fit Pro-M frame or 2nd gen m frames. 

These are new, but came out of a frame at one point.  The only marks on these is where they meet the sunglass frame as it would be when inserted into your frame.  

The other rarity of these is they are an amber base lens.  Fire Iridium were mostly made with the grey base.   These lenses are few and far between.
