These are plastic, but they look great on the door and are so easy to install. Love that they are magnetic, as opposed to having to drill holes in the garage door.  Our only problem is that there is not enough clearance in the trim around our garage door to allow for these, therefore they would catch if we tried to open or close the door. We're getting new siding on our house soon, so hopefully this can be adjusted then! Very pleased with the product, but recommend you check the clearance around your door before ordering!
