Indeed at one time ! To much love for em ! I was going to trade them In with a busted Ducati for a new pair ! Never plan to sell ! Kinda weird having someone else wear my body oil’s these Canot be cleaned ! These were mint condition when I got them much love much use ! lolHonestly that's kinda tough! even though you still have the serial Number on nose bridge intact, the value isn't the same because of the missing stem. I think you have misplace them somewhere? If I recall, wasn't these being sold somewhere with 2 set of stems and matching box.
