Unless your friend knows @THE X-MAN I would NOT trust him with those sunglasses unless you don't mind them being destroyed.My friend told me that theres someone he knew could fix the loose parts using precision tools like oakleys..it cost 30 dollars is it cheap?judging from what ive told u about the condition how much will i spend to make it look like yours?by the way your piece is awesome!!
I know a friend who can fix anything too but I still would never never let him touch any of my x-metals. If I had to send them to someone I would send them to THE X-MAN
It is your decision though.
