The pictures show more than one pin to see it from different angles but the $4 is for one pin. This pin is commonly called a lapel pin. The decorative part has a pin to put through the fabric; the second part is a butterfly clutch you put behind the fabric to hold it in place. The pin can be used to fasten a fabric belt or anywhere on the dress for an accent piece. It resembles a button. The pictures show the nickel pin which has a raised part of bright nickel with a brushed or foggy background. On the black pin, both the raised part and the background are flat black.
