1. When using it normally, pay attention to whether there are any problems such as "breaking belly", "de-toothing" and skewing on the zipper. If there are any problems, repair them in time and do not pull them hard. If the zipper is loose and toothed, use a small hammer to tap a few times on the zipper head to make the upper and lower chain teeth bite tightly, and then no more teeth will be removed.

2, the zipper of aluminum alloy is more susceptible to corrosion, so it should be kept dry, do not get damp, to prevent the aluminum tooth from forming white oxide, which will cause zipper rust and affect the use for a long time, but Keep a certain degree of ventilation during storage, do not seal it, do not store it in a humid atmosphere, or use moisture-proof paper or dehumidifier if necessary. If the zipper is damp And pulls up, then the zipper will be exposed to the sun, then some wax will be applied to the zippered teeth, and then fired, so that it is very lubricated.

3. When pulling the zipper, first align the teeth on both sides, then pinch the zipper head and gently pull it forward along the track. Do not forcefully pull it to avoid "tooth skew", "breaking belly" and "toothing". If the zipper is bun and the pull is not flexible, you can wipe it with a cloth and then apply a layer of white wax on the "teeth".

4, all kinds of bags, pockets or wallets with zippers, do not overfill, otherwise it is easy to cause the zipper to "break the belly", "toothing", skew and soft cloth
