Query: Great Quality, but Cards Slip out Easily

I've had this card holder for 3 years now, and it's worked great. Only detail is that the rubber insides don't hold the cards very well, and if its been jostled around they may fall out when you open it up.Just wanted to give a heads up for anyone looking to use this in outdoors/photography situations.
