The thought of carrying loose cards in my pocket for some reason makes me feel sick, I've always been a small wallet guy, I recently got this wallet and I can't say it changed my life but its nice and slim without being an awkward card holder. I carry this, my phone and my keys, I've read comments recommending ditching keys you don't use everyday but when I tried this I ended up at work without the key to my bike lock.
