The Leather Ruler from Jung-Woo Lee is a simple twist on an old school design. This ruler features a sheet of leather that can be used for steadying or as a carrying case.
Carrying around a ruler in your pocket means that you're happy to see someone, and that you kind of look like a geek. The Leather Ruler rolls up, disguising your ruler to the world and matching your leather chaps and jacket at the same time. Fashionable innovation is always a win.
