Answered: Zip ties allowed?

Hi! I’ve browsed the web for an answer, but none were concrete, so I’m posting here. For our team we have these large colored zip ties that we bought from the local convenience store. We only use these to manage our wires. They are in different bright colors and are longer and thicker that normal black ones. Are they allowed?

If these are only being used for cable management, they would be legal as per <R7l>, quoted below (some text bolded for emphasis):
