The 25 ½-inch Jacket Zipper is available in 8 colors! The length of the top stop determines the listed zipper length to the bottom pin and box. The tape extension is not considered in the measurement. Separating zippers are designed so the two sides of the tape are able to come apart completely after the zipper has been installed. These Jacket Zippers feature a polyester coil with a separating bottom pin and box. Ideal for both clothing and accessories. Use them on jackets, sweatshirts, and more.
