Razor cover
When leaving home in a hurry to catch a flight, you tend to forget the things you don’t usually use. You probably won’t forget your razor blade, but you might forget the plastic cover that comes with it (even though you know exactly where it is).
This looks like an accident waiting to happen. Imagine putting your hand inside your toiletry bag with an uncovered razor. A binder clip is an easy way to prevent a bad situation; put it on the razor to avoid accidents. You probably have one lying around your office.
