YKK zipper metal bright light high-grade handbag zipper

If the metal zipper breaks down in use, it must be repaired in time. The metal zipper has the phenomenon of "tooth off" or "skew", which can remove the bad teeth and add new teeth, which can still be used; When the metal zipper head is pulled up, the teeth on both sides do not close, which indicates that the metal zipper head is loose after wear. You can gently clamp it laterally at the closing end of the metal zipper head with an ordinary vice, and the metal zipper will immediately get better, and the teeth on both sides will close tightly and no longer crack.
If the metal zipper head cannot be pulled, it indicates that the clamping force is too large and must be adjusted again; Some metal zippers have two teeth falling off, which can separate the tooth falling off parts, move the metal zipper head inward, fix the end with needle and thread, and continue to be used; If the teeth of the metal zipper and the metal zipper head are not metal and are broken, they can not be repaired, so they have to be renewed.
