Definition
A drawing pin, similar to a thumbtack, is a short pin with a broad, flat head used for fastening papers or lightweight items to a surface, typically a bulletin board or wall. It is designed to be pushed into the surface by hand. The terms "drawing pin" and "thumbtack" are often used interchangeably, though "drawing pin" is more common in British English. Think of it as a small, easily removable fastener. It's a convenient way to display notices or artwork.
