About as minimalist as a bifold can get, its made from a single piece of leather. I like minimalist pieces but I tend to carry bills more than cards so I prefer a bifold over a card holder most days. This was my solution for a minimalist bifold. It has a bill area and 2 card slots that can hold multiple cards each.
Leather is a natural product and as such it will vary from piece to piece. Grain size, scars from bug bites, brushes with barbwire fences, etc are to be expected. Its part of the beauty of a natural product.
