A zipper is a common fastening mechanism used in jeans. It consists of two rows of interlocking teeth that are pulled together by a slider. When the slider is pulled up, the teeth interlock and the zipper is closed. When the slider is pulled down, the teeth unlock and the zipper is opened.
Zippers can sometimes become jammed or broken, which can be frustrating. However, there are a few simple steps that you can take to fix a zipper in jeans.
