This is a set of 2 (Driver's side and passenger's side) laser-cut, mirror stainless steel trim pieces that adhere to your rear side-markers to accent the side-markers. These do not adhere to your car's paint. They adhere to the side marker lenses themselves. These will come with pre-applied 3M double-sided automotive tape. Simply clean the area with alcohol, peel the liner, and carefully stick into place and press firmly.
