Invisible zipper is a kind of zipper that is not easy to detect. It is commonly used in clothes, bags and other items. It is characterized by the fact that the zipper is almost invisible when closed, making the overall appearance more concise and beautiful. This type of zipper is usually made with special technology, which can be easily opened when needed, and then fully integrated into the surface of the item when it is closed. Invisible zippers usually use delicate zipper hinge and zipper head design, as well as precise production technology, making them almost imperceptible in appearance.
