What is the difference between the Slimstar with small coin pocket and the Slimstar with large coin pocket?

As the name suggests, the Slimstar with small coin pocket has only a small pocket for 1 to 3 coins. The wallet is of course much thinner. This Slimstar was designed for people who don't really want to have coins in their wallet. The Slimstar with large coin pocket, on the other hand, is designed for people who like to have their coins in their wallet.
