A rubber band is a loop of rubber that is used to hold objects together. It is stretchy and can expand to fit around various items, making it a versatile tool in everyday life. Rubber bands come in different sizes and thicknesses, allowing them to be used for various purposes, from bundling papers to securing items in place. The material used to make rubber bands is typically natural rubber or synthetic rubber, which gives them their elasticity. They are commonly found in offices, homes, and schools, and are often used in crafts and packaging. Rubber bands are a simple yet effective solution for organizing and managing items.
