This is a pocket protector for my two favorite screwdrivers, a pencil, and a pen. I love to carry them with me and its always handy having them on me, but carrying them around puts holes in my pockets, holes in my pants, or holes in my leg. Its not super clunky but its intended for a front pocket carry. It's got quarter inch markings on the side to use as a ruler in a tough situation. This case is perfect for my every day carry (EDC) but its not likely to exactly fit your needs. I encourage you to remix the idea to fit your needs!
