Invisible zippers are a type of zipper that is hidden from view when closed. Invisible zippers are commonly used in garments, such as dresses, skirts, and pants, where a visible zipper would be unsightly. They are also used in bags, luggage, and other items where a hidden closure is desired.
Invisible zippers are made with a special type of zipper tape that has fine, closely spaced teeth. The teeth are hidden from view when the zipper is closed, giving the appearance of a seamless closure. Invisible zippers are typically sewn into the seam of a garment or item, and they can be either hand-sewn or machine-sewn.
