Design
We use nylon to make these wallets since it's typically thinner and lighter than leather. The design of the nearly seamless look was achieved by our designer Nik through a process similar to that of origami. He had to imagine and conceive of a series of internal folds that would — after the final action of turning the wallet inside out post-construction process — create pockets for cards/cash and achieve that seamless look. The wallets are also slim enough to fit comfortably in your front or back pockets.
Wallet #1
Nik's original wallet and the most minimalist of them all. Two interior fabric pockets. No exterior pockets.

Wallet #3
Two interior pockets: one is fabric, the other is clear urethane. And this time, there's one exterior pocket.

Wallet #4
Wallet #4 is exactly the same as Wallet #3 except for one key difference: a small webbing loop through which gives you the ability to securely and conveniently tether this wallet to any TOM BIHN bag with O-rings. You'll need a Key Strap to do this, but given that all of our larger bags come with one 8" Key Strap in Black, you probably already have one. If you don't: see our various styles, lengths, and colors of Key Straps here.

Wallet #5
Two interior fabric pockets and one exterior pocket. Basically, it's a Wallet #3 with a fabric pocket instead of a clear urethane one.
