The one that started it all, the slim wallet, my first ever design, made from one piece of leather, with minimal stitching, a place for bills, and two card slots that carry at least 4 cards in each.
I wanted a front pocket wallet that wasn't just a card holder but had a place for unfolded bill. Took a piece of leather in the shoe factory I worked at, and made this in the first try, I love how it came out and it started SIMPLE leather!
