Beware of credit cards

I now have the bag for 3 months and am actually very happy. The build quality and fit are very good. The magnetic locking mechanism is working properly. But therein lies the problem.
The inside compartments are designed for bills and credit cards. However, care should be taken for credit cards on where the magnetic strips is when inserting !! If the credit card "wrong" plugged in, the magnetic stripe is located just above the magnetic closure ... and thus destroys the credit card. So I no longer püassiert, the subjects I've marked with a pen. Viewed over all the value for money is but Ok.
