I have always been partial to small thin wallets. My first wallet from when I was in grade school was a brown leather simple two pocket card wallet that my dad gave me. It held my ID, a little cash and a house key. Oh the good old (and simple) days! It was so thin and flat that you would be hard pressed to tell I had a wallet in my pocket. Different story if I am just happy to see you... So my whole life, I have been using these small thin card wallets. Each for a long time. The one from my dad, I carried until my late 20's. Then I got a thinner leather one, but with one accordion pocket. Been using that until this year. It is very functional and simple. It even holds a load of survival gear. Only problem was if I drop it, things can spill out. Fortunately, only happened once in all these years. And at home. For whatever reason, I felt like a change and I heard about Belroy and checked them out. I likey it! Card Pocket - Slim Leather Wallets by Bellroy It holds slightly less than my fold over wallet, but is smaller and more secure. Here it is with a Space Pen for scale on my orange bandana. It holds my cards, spare cash and some survival goodies. The survival goodies... A fresnel lens that is 25 years old (will put a new one in maybe), a bandaid (because monkeys ask for them sometimes), a piece of cotton batting cord, an original brass Sparkle, and some Spiderwire (gotta be at least 30-50 feet) wrapped around a piece of thin cardboard. In my older, slightly larger wallet, I had a longer piece of cord running through a brass tube, two tinderquick, a piece of sandpaper, and a small coil of wire. Maybe I will add more stuff to this one later. But I like the neat size. Anyway, to me, it is a cool wallet and very well made. So far, I am liking it.
