I think many people have had to deal with the fact that the parking sign is not visible from the interior of the car. Either it falls down all the time or it blocks the view. And with this holder from Tbuymax such problems will not arise! The handicapped parking sign frame itself measures 10.6 inches by 5 inches - absolutely any standard sign will fit. Your sign is now securely protected from scratches, bends and tears. The hook conveniently attaches to your rearview mirror, providing plaque protection and universal use in any vehicle. Transparent plastic keeps text clear and is easy to install for convenient use.
