Enclosed Keycard Holder

My access keycards and transport cards seem to get damaged over time when used with those generic lanyard card holders which leave the cards exposed to the elements. So this is a single card holder that can shield my access cards while still being semi-transparent enough for me to see what it is. The cage that holds the card is reversable when inserted into the sheathe, and the sheathe has a nub which clicks down onto the cage no matter is the card is facing in or out. The slot at the top is moderately sized to fit most lanyard clips I've tried. There's also a cage variant which opens up the back cavity so that a center rectangle of the card is exposed. If you don't like having your card visible from one side or at all, you can always use opaque filaments. I that would do great for my keycard so I don't have to look at my terrible photo.
