Rubber bands are flexible loops made from natural or synthetic rubber. They are commonly used to hold items together, such as papers or small objects, due to their elasticity. When stretched, they can expand significantly and return to their original shape when released, making them useful for various tasks. These bands come in different sizes and thicknesses, allowing for a range of applications. In addition to office use, rubber bands are often found in kitchens, workshops, and even in crafting. Their versatility and low cost make them a popular choice for organizing and bundling items efficiently.
