The Stanton is a classic. It’s small enough to throw in a clutch or front/back pocket, but has 5 pockets, which lends itself to a nice amount of organization - no shuffling through cards to find the right one. It's a little bigger than the Osgood and has a slimmer profile than the Essex. A great go-to for gifts, as it stands in that middle ground but still holds a lot.
A lot of folks use these as secondary wallets to their primary bifold, so when they need a smaller option (especially for a night out in a suit) they can switch to this guy!
