#4 Invisible / Concealed (Heavier-Duty) Nylon Closed-End Zipper

#4 invisible / concealed nylon closed-end zippers are heavier-weight than standard invisible zippers and measure just over 4mm across when zipped.    These are true invisible zippers - when the zipper is sewn into a garment, the zipper teeth do not show.   These zippers do not separate at the bottom, and are available in wide array of colors.   Looking for longer lengths? See our product listing for #4 invisible continuous zipper chain to create any length zipper you want!   Custom colors are available on a made-to-order basis. MOQs will apply. Please reach out to us for more information.
