Mmmm-hmmmmm. Gotta have something to keep that Chicago Wad organized.
Skinny. The thinnest I can find. for a while I gave up on leather wallets. I have bought a couple at the Amish store locally for a dollar that are nylon. They’re VERY thin, but they don’t last. I even used a business card wallet thingy for a while.
I’m now on some bifold. Thin enough and has enough compartments here and there and the main bill area has a divider.
