Photoetched parts are parts made from sheets of metal and provide an excellent way for modelers to add extra detail to their models which can't always be done in plastic.
Photoetching is a process whereby the sheet metal is exposed to chemicals which erode or etch away the metal which has not been treated with a special resistant ink. So any metal coated in the ink remains to form a part such as a seat belt buckle or brake disc - these usually come with multiples of or other parts to form a fret as sold by Studio 27 to name one.
