Vintage 80's and 90's accent trim from Newstar.  These are "CAMARO" with a bowtie.  These are new old stock and no longer in production.  Each piece is roughly 5.15" wide x .51" tall and approx 1/16" thick, and would typically be installed inside the door handle recess (assuming your handle has the space), however, you can install them wherever you like : Dash, Door Panel, Fender, Spoiler, etc.  You will receive a sealed card containing (2) accent trims as shown. These are a peel and stick application, however, with these being 20-30 years old, you may need to use double stick tape or glue to affix.
