Permanent means permanent, right? Not necessarily. It’s difficult to remove permanent marker from plastic, but not impossible. Here are several ways to get permanent marker off plastic.
The favorite trick is coloring over it with a dry erase marker, then erasing it. But if this doesn’t work, or you don’t have a dry erase marker, there are other solvents and cleaners that can also work. On cloth, permanent marker really is permanent, or nearly so, since it can soak into the surface. On plastic it can’t, so permanent marker is more like semi-permanent on plastic.
