It is illegal in all states to drive with your handicap tag hanging from the rearview mirror, but it is not easy to hang and remove the placard as required by law. Mirortag is designed to protect and preserve your tag. It allows you to easily display and put away your handicap parking placard. Simply insert your tag into the plastic holder, place the hook on rearview mirror once. When parked, move plastic holder close to hook and the magnet will snap onto the metal plate of the holder to hold the placard in place. Before your drive, simply pull down the plastic holder to unlatch it from the hook. MirorTag Silver has a super strong magnet that keeps the placard and hook held together. Unlike all flimsy sheaths, it has a detachable sturdy hook that is sun & cold-resistant and will not break or we will replace it free. Holder will protect your placard from cracks, tears and creases. Extra hooks can be purchased separately for multiple cars. WARNING: rearview mirror built-in compass operation may be affected by the magnet in some car models. 2 holders and 2 hooks included. Sale is for holders and hooks only and placard is not included, and shown only to clarify how to use it. Patent pending and Made in USA.
