<human>:  How can I repair a broken zipper?
<bot>: To repair a broken zipper, you will need a pair of needle-nose pliers, a pair of scissors, and a zipper repair kit. Start by carefully examining the zipper, looking for the broken parts. Once located, use the needle-nose pliers to remove any bits of fabric or thread that are stuck in the zipper. Once everything is clear, use the scissors to carefully trim off any damaged ends. Then follow the instructions in the zipper repair kit to install the new teeth or zipper pulls.
