The Zipper Slider, mesh 3 and in sapphire blue, 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 3 corresponds to the standard thickness of the zipper teeth, making it essential to choose the slider with the correct mesh to ensure smooth sliding. The sapphire blue tone, more intense than conventional blue, highlights zippers in clothing and accessories with a more vibrant style. It is a small, indispensable repair accessory for anyone who works with zippers in sewing and leather goods.
