Full disclosure, I'm a Renn Faire dork. I switch between some elaborate costumes, or a casual Scottish outfit with my clan colors. I usually use a sporran pouch for every outfit to carry basic gear, but lately realizing my fantastic Saddleback wallet is just too big to justify carrying around in a small leather waist pouch. Accordingly, I just carry my ID, a credit card, some bills, and a few business cards in a velcro pocket on the outside of my sporran pouch. This quickly has become chaos. Bills wadding up in half, credit card falling out, business cards in the way...I need a thin, minimalistic wallet that can slide into this outer pocket and keep things somewhat organized. Affordable as possible please, color and appearance does not matter because of it being an internal organizer.
