Zipper

A zipper is a fastening device used to securely close and open items like clothing, bags, or tents. It consists of two rows of small metal or plastic teeth that interlock when the slider is pulled down or up. The slider moves along the teeth, guiding them to engage or disengage, effectively closing or opening the item. Zippers are convenient, durable, and quickly provide a secure closure, making them a common choice for garments, luggage, and other items requiring a reliable opening and closing mechanism.
