Start by checking the back of the broken zipper slider to see if there’s a number indicating the size. If you can’t find a size marking, you can measure the height of one of the zipper teeth and the full width of the zipper when closed. Also, look at the shape to match it with the correct slider. Use a pair of pliers to remove the old slider — make sure to grip it close to the base. Open the new ZlideOn slider and attach it to the zipper by snapping it shut. Done! You can click the new slider onto the start of the zipper or at a section where the zipper is still joined. If neither of those options work, you can cross the two sides of the zipper and snap the new slider onto the X. Hold the ZlideOn closed for about 10 cm while zipping up.
