For Safety Glasses
I bought this product thinking that it would be big enough for my safety glasses, but they hardly fit.  These safety glasses are not the big ones that go over normal eye glasses... just the ones that are for the naked eye.  The case is just flexible enough to force the glasses in, but rigid enough to make me secure in thinking that they can withstand most impacts when packed in a soft-case suitcase for flights.  My costa del mar sunglasses fit fine, and my normal day-to-day corrective eye glasses fit fine as well.
