I have a Valextra that I picked up from Off 5th. It's a bifold, black, 6 card slots, very basic wallet. It doesn't look all that special but it seems to be fairly durable for how thin it is. It's actually kinda hard to find a leather bifold that is both durable and thin IMHO.
My previous wallet was a black LV Epi. That thing will probably outlast me, but was too thick to sit on, and too thick to even put into some of my blazer inside pockets. It now sits retired in my closet until I work up enough drive to sell it.
