functional, not optimal
the 2 pieces of the case seem fairly sturdy though the hinge that holds them together is not quite as sturdy. I bought this alone with a pair of the Gunnar Intercept glasses and they do not fit particularly well. They are large glasses and it may be possible that some of their smaller products would fit better (i do not have any of their other glasses to test this with). Also the magnetic locking/closing mechanism  is not very strong, so even though it will close around the Intercepts it will not really stay closed.
