The proposed Amazon Glasses for 3D glasses is unfortunately very small dimensions and tight! As a protective measure for the rather expensive 3D glasses Panasonic I imagine a more comfortable spectacle! The glasses fit with press on the outer shell in the case, if that's the point of it, it's just bad !!! Keep the cases just because I do not have time for a've so much longer to stop and my return costs would be incurred that are too good to me! I would not buy these cases again!
