MirorTag™ Silver MTD100 is designed as a handicapped parking permit holder, hanger, sleeve or cover to protect your disabled parking tag, sticker or badge, and most importantly to eliminate the need to hang and remove the tag from/to rearview mirror post every time you park and drive. Simply insert the hook onto the rearview mirror post one time only and leave it there. It will be hidden behind the mirror and will not block your driving view. When you park, bring the placard holder metal square close to the hook's magnet on the mirror and the super strong magnet will attract the holder and firmly hold your parking permit placard in a displayed position. Before you drive, pull down on the placard holder to unlatch it from the magnet. Your handicap parking placard will be protected inside the durable plastic frame, and you no longer need to touch it.
