Thank you for viewing. This is a set of two Daihatsu genuine number frames. These are made of plastic. I will also include four McGard number lock bolts, which are Daihatsu options. The size of the license plate is the same for both kei cars and regular cars, so they can be installed. Kei cars can be installed as is, but for the rear of regular cars, please remove the seal before installing. Please note that the product is thick, so it may be simply packaged. It will be sent by Yu-Packet Post and delivered to your mailbox.
