I recently purchased a leather card holder and I`m very happy with my purchase .It's the perfect size to fit in my pocket without being too bulky, and the removable window is a great feature for swapping out my ID. the genuine leather adds a touch of sophistication to my everyday look. The only DOWNSIDE is that it may not fit all of my cards, but I can easily switch them out as needed. Overall a great addition to any man's fashion accessories collection..
