A binder clip is a simple tool for holding pieces of paper together. They are usually made of spring steel. They are usually found in office workplaces. They also have other uses, including bookmarks and wire clips. To use a binder clip, push the back two silver handles together to open the black clamp, insert the paper in the opening in the black clamp, then then let go of the black handles and release the clamp to hold the papers together.
