Magnetic Cable Tie 3-Pack, Yellow, Replacements for use with MOS Organizer

I originally backed the MOS Cable Organizer when it was a Kickstarter project. It came with a few of these cable ties and then I have ordered more. Although the magnets are not strong and wouldn't be suitable for some other uses, they work great with the magnetic MOS base. I like that they have different colors and also that they are a neat unobtrusive way to manage cables quickly.

not strong enough to hold a cable in place if the base is mounted vertically

Good idea, works well.
