The Zipper Slider for Cose zippers, mesh 5 and in black, reference 367303, is the sliding piece that runs along the teeth of a nylon zipper, used to replace broken or lost sliders without needing to replace the entire zipper. Mesh 5 corresponds to the standard thickness of the zipper teeth, making it essential to choose the slider with the correct mesh to ensure smooth sliding. This alternative reference in black corresponds to a different slider model within the mesh 5 range, maintaining the same color versatility. It is a small, indispensable repair accessory for anyone working with zippers in sewing and leather goods.
