Each BADGE magnet contains 3 powerful magnets that can hold securely through thick layers of material, preventing tearing/puncturing of your shirts/blouses and maintaining a professional appearance.The badge magnets are so much more practical than the pinned-on badges that ruin your clothes. It is so much easier to attach your name tag or badge to your shirt/blouse and it holds well when you wear it.
The 1.5mm thickness of the washers is designed to accommodate a flat-head screw, so it does not sit proud and interfere with the required flat connection to the magnets surface.
