CableDrop

Let’s face it: the underneath of your office desk is a gigantic mess. Not only that, your MagSafe and USB hub cables just won’t stay on the cable when they’re not plugged in to your laptop, and the tape job you’re using to hold it all together isn’t pretty.
For this, CableDrop was invented: small, adhesive plastic holders to facilitate your cable management. They hold the cable tightly enough to keep it from falling, yet provide little enough resistance so that you can pull it through to plug it into your laptop. They’re available in a variety of colours and sold in packs of 6.
