Rubber bands are flexible loops made from rubber, a stretchy material that allows them to expand and contract. They are commonly used to hold items together, such as stacks of paper or bundles of pens. Their ability to stretch makes them very useful in everyday tasks, from organizing office supplies to securing items in a bag. These handy tools come in various sizes and thicknesses, making them suitable for different purposes. For example, larger rubber bands can be used to hold together books or folders, while smaller ones are perfect for keeping hair in place. Their versatility and simplicity make rubber bands a staple in homes and offices alike.
