I love this KableFlag Cord Labels. They are the most simple and efficient way to identify the cables. These adhesive-free PVC tag which wraps around the cords allow us to see the cables easily. Kableflags are available blank so that we can create our own custom labels with a permanent marker or you can also get pre-printed ones which comes in a pack of 10. With them, you never have to unplug the wrong cables again.
