Not quite clear as intended

The card case is great in general. The retractable tape has the proper tension: I did not difficult to draw the tape to the card then to keep the shell to the reader, and it will also bring back good returns.

The carabiner could be slightly larger, as well as my belt loops on the pants are a little wider.

Moreover, I find the shell not as transparent as I expected (I had similar cases).

Basically, five star, but because of this little flaw a star deduction.
