You have an outlet with 6 devices near it. They all have the same color
cords. You sometimes unplug one device to plug in another.
It's not always clear which cord goes to which device. You're worried about
unplugging the wrong device + you're not sure if you're plugging in the
A little packet that has pairs of color coded tape/wrapper/clips etc so you
can mark the cord in 2 places: near the plug end and where the cord comes
out of the device. So there's no ambiguity about what item you're plugging
in / removing.
