How to fix a broken zipper?
To fix a broken zipper, first identify the issue: a misaligned slider often requires gentle plier adjustment to its top and bottom plates by 0.5mm, while bent teeth can be carefully straightened using needle-nose pliers. For a completely separated track or a damaged slider, a replacement slider from a dedicated repair kit, matched by its size number like a #5 or #7, is typically needed and involves removing and reattaching the bottom zipper stopper.
