Step 2:
Using the pliers, tighten the mouth of the slider.
You want the space to be tight enough for the zipper to close.
But ensure not to pinch it too tightly, otherwise, it will get stuck.
check that you hold the end while zipping.
This will prevent the slider from sliding out of the teeth and keep it nicely secured.
