Hello! I recently bought one but ended up returning.
The first one I received- bad quality.
Second one- much better quality. I put 12 cards in total + a few coins coins and when I closed it, it was like zipping up jeans when you've put on a quite a few pounds

the whole purse was so tight/stiff (might have been because of the coins). I'm sure this will loosen over time as i've seen people fit more than that, but what i noticed (and also seen on youtube videos) is that if you put cards in the back slip pockets (ie the one behind the card slots and closest to the outside of the wallet) you can see the imprint/edges of your card on the outside of your purse and I really didn't like that. Anyway for me £310 wasn't worth the spend so I returned it. This is just my opinion and experience of course!

Overall it is a nice compact wallet that will fit in any bag. Maybe consider the Rosalie wallet? Especially if you're not one to be reaching for cards on a daily basis (i'm always using my phone to pay), it's a cheaper alternative to the ZCP and about the same size if not a bit smaller, but with less compartments.
