First, I bought the "Tony the Ant" version because I was intrigued by this design, then I bought the "Fat Herbie and I love it, was love at first sight, I've placed 16 cards and the wallet is still impressively thin, it is a little bigger than what we usually understand as a "wallet" but it is precisely that size that makes it unique and special, now I will use the "Fat Herbie" model for daily use and to go out in dress pants or occasions that I need something that goes unnoticed I will use the "Tony the ant"". Best of 2 worlds in the same style. Love this wallets.
