Earphones/Power Cord Rollup Storage

pinshape

I created this because I got fed up with my earphones and power cords constantly getting knotted. All you need to do is open the ball, insert your earphones or power cord into the middle, and then twist the two halves in opposite directions for it to neatly coil up inside. There's plenty of room for refinement - I'm already thinking about making a flat version specifically designed for earphones, complete with a clip that allows you to attach it to your shirt, sweater, or pants during runs or walks. Eventually, I also plan to add a spring mechanism so the coiling process happens automatically without needing manual intervention.
