The Cose 22cm white invisible nylon zipper is a pre-assembled zipper with a slider included. Its teeth are hidden behind the tape after application, leaving only a discreet stitching line visible. It's the most commonly used type of zipper for dresses, skirts, and blouses in more elegant clothing, where a clean finish without the zipper being visible is desired. White is one of the most sought-after colors for light-colored dresses and blouses, where a zipper of a different color would be visible through the fabric. The 22cm length is suitable for skirts and dresses with short openings, usually applied to the side or back of the garment. It requires a specific invisible zipper foot on the sewing machine, which allows for correct application along the hidden teeth.
