Basically like this: pinchandfold.co.uk/collections/wallets/products/suri-wallet-blush
I can't find one I like that is small enough to go in a pocket but also has plenty of space for cards and notes. Plenty or at least space for 2 or 3 cards anyway! Preferably leather.
I'd rather not spend too much, up to £35 maybe. I'm easy to influence though so post whatever fits the bill.
