Most:
does not swell when you fill it.
NFC protects your credit card for potential hackers.
compartments to store your cards, paper, money, etc. by category .. ideal for maniacs!
very aesthetic, and seems robust. See the use in time.
Cons:
does not swell filling .. so limited in the number of cards / paper / tickets that can be put there. Enough has largely if not all the loyalty cards of our dear "Super".
The size limit for a very CNI and a driving license. Unable to put a gray card (if one does not want to fold on the length).
Very good product, I recommend!
