The Proove Metal Lock is a parking number plate designed to let other drivers contact you if your vehicle is blocking their way. It features a combination of metal and plastic in a compact 8.5 x 17.5 x 126 mm frame, ensuring it fits neatly on your dashboard without obstructing your view. To help people find your number at night, the digits are finished with a luminescent coating that glows in the dark. For those times when you prefer to keep your contact details private, you can simply use the magnetic slider to cover the phone number. The package includes the parking card itself along with five sets of reserve numbers so you can update the information as needed.
