Pushpins are a staple office item used to secure papers and notes to a bulletin board or wall. However, there are several synonyms for this everyday tool, including thumbtacks, tacks, push tacks, map pins, notice boards, cork board pins, and bulletin board pins. Thumbtacks feature a flat, round head with a sharp point, while tacks have a long, pointed end and a flat head. Push tacks have a butterfly-like shape, while map pins are often used for cartography and feature colored heads. Notice board and cork board pins typically have a plastic or metal head with a pointed end. Whatever you call them, these small and handy little tools are essential to keep things organized.
