Simplicity and high quality are what appeal to me. The cheapies don’t wear well. And I definitely prefer bi-fold since they’re flatter in your pocket than tri-fold.
This is what I love about FR. Lots of great advice (which is of no help, since no one agrees) and lots of even better humor. Love the Ballad of the Unloved Condom.
I’d venture a guess too that the expensive from Nordstrom will not only outlast, but will also be happily exchanged if you missed the mark, or refunded. Cheap stores don’t have the class that Nordstrom does. You pay for service at Nordy’s, and you get it.
I don't like the tri-folds for that reason. They can get way too thick easily. Also, get one that has a separate pocket for just a driver's license and another ID or picture.
