These are great little cable ties. They are strong enough to hold a power cable but light enough that you can cut them off with scissors instead of wire cutters that you need with a heavier tie. They are suitable for USB and cell phone type wires, they really aren't long enough for power cables. At this price for this number, you can afford to just cut them off and use them instead of twist ties.
