How would you describe the zipper?

A zipper is a fastening device commonly used in clothing, bags, and various textiles, consisting of two strips of fabric with interlocking metal or plastic teeth and a slider that opens and closes them. It allows for quick and secure closure, making it practical and convenient. Zippers come in various sizes and styles, from heavy-duty versions for jackets to finer ones used in dresses. Their design has evolved over time, but the basic mechanism remains largely the same.
