Magnetic clips are useful aids in office organization and communication. Having a clip on the meeting room's bulletin board or on the refrigerator at home lets supervisors and moms alike post full-length notes, memos, and safety sheets where everyone can see them. Even on a desk, away from the magnetic surface, almost all clips and fasteners will hold together a stack of papers or seals closed a bag of chips in the break room.
One of the nice aspects about these fasteners with magnetic backing is that the magnet isn't picky, as it easily adheres to any ferrous surface, usually iron or steel, and it stays there until moved. That makes the handy office supplies effective tools for posting pictures and notes to refrigerators and dishwashers, as well as putting up announcements and Materials Safety Data Sheet (MSDS) paperwork near hazardous materials. They're also really helpful in common areas, such as in changing rooms or next to time clocks, for hanging ID lanyards or keys to company vehicles.
