The Allett wallets keep the cards in safely, as the card pockets open inwards, i.e. when the wallet is folded closed the cards are safely held inside, and in the last few years added a rubbery grippy thing to the card pockets to keep the cards from falling out when the wallet is open for use.
Wow! You win the best customer award! Thank you and thanks for your post. The point you mentioned here is key. The card pockets facing inward and the grip inside the card pockets really do wonders.
