The quality of construction and the materials are excellent, but the reason for its existence, to provide convenient storage for your cash and cards, is a failure.  The arm mechanism that holds the bills into the wallet is constantly flipping up and releasing the bills.  Also, the thing is so stiff, even after a few months of use, that it will not actually flip fully open.  I hoped that it would loosen up and function, but it has not.  I wish that I had returned it.  Too late now.
