Secridmini wallet genuine black leather with RFID protection/with one click all cards slide out gradually

Can the metal and leather parts be separated (and reattached)? E.g. for just using the metal part on a day to day basis.

How is the size for front pocket carrying?

How many cards can it fit comfortably in the slide up part and how many can fit inside the wallet without it being stuffed up too much??

Is this the original Secrid Wallet?
