No. 3/4.5 YG Slider Metal Zipper

Why girls Jean's have a zipper? And what is it made of?

Zippers on a boy's trousers are for convenience, but what is a zipper on a girl's trousers for? 

Obviously girls can't stand as convenient as men! There are many theories about this answer. 

Some people say that the zipper on jeans is for decoration, which is a retro feeling that cannot be changed. If a retro boutique like jeans does not have a zipper, it is not a jeans. 

Some people also say that the zippers on girls' jeans are also for convenience. Women's bodies are different from men's, their hips is bigger, and the Jeans Zipper gives more elasticity, and if there is no zipper, it will be difficult to wear jeans. 

Cost savings should be a particularly pertinent statement. If a pair of jeans is made specifically for women, a new design is required, which means that the production chain needs to be reworked, and the process is very expensive. Moreover, the design may not necessarily be popular.

The Zipper For Jeans is made of metal, which is called Metal Zipper, normally with brass material teeth and polyester tape. The size of Metal Zip is normally #3 or #4.5, also called as YG Slider Metal Zipper or Jeans Zipper. The brass material teeth is durable, there are normal shape and Y shape teeth, the Y shape teeth is more strong but cost is little higher than the normal one. To choose which shape of teeth of Metal Zipper, it depends on your market needs.
