Basically, those zippers that do not have their trademarks engraved on the bottom mold of the zipper (that is, the back of the zipper) are all brand-name zippers. Because genuine zippers now require their trademarks to be engraved on the bottom mold or pull tab, firstly for advertising effect, and secondly to prevent counterfeiting.

Of course, there are some with engraved trademarks, but they are also miscellaneous brands.

When we buy clothes, we mainly look for international zipper brands such as "YKK" and "YCC". Secondly, there are domestic brand zippers such as "SBS" and "FFF". These are the better brands.

The zippers used in good clothing are all made of YKK or YCC
