The One-Wrap thin ties are great. Reusable zip ties. I use them for so many things: bundle computer, speaker, stereo, etc. wires together. Tie garbage bags so I can reuse in which I store Christmas decorations. I put one on each extension cord to hold together when not in use. I use on lamp and other cords to take up the slack.
So many uses and re-uses. Go ahead and buy 2.
