When my Oakley is not in use... 
 
they are stored in my own DIY metal vault briefcase. Super tough and one swipe is enough to maim any ill-intended individuals. 
 
 
 
 
 
 
They are not perfect though but I feel they're better than the Oakley metal vault. I just need to find a piece of metal and engrave the X metal logo before rivetting the damn thing on the sides of the case. Anyone has a ready jpeg file for the X metal Logo???
