The Milward Concealed Invisible Closed End Zip is designed for dressmakers and tailors who require a seamless, professional finish for skirts, trousers, and dresses. Its primary benefit is the invisible coil design that blends into garment seams for a clean, sophisticated look; however, users should note that installing concealed zips requires a specific presser foot and precision sewing to ensure the fabric edges roll correctly for a truly hidden appearance.

While technically possible, a standard zipper foot will likely leave the coil visible. A dedicated invisible zipper foot is highly recommended for best results.
You can move the adjustable stopper by carefully removing the metal crimp and re-securing it, or by sewing a new bar tack across the bottom of the coil at your desired length.
The no. 3 nylon coil is lightweight and best suited for dressmaking fabrics; it may not be robust enough for heavy-duty denim or thick outerwear.
Milward offers a consistent colour palette, but it is always best to hold the zip against your fabric in natural light to ensure a match.
It is generally not necessary, but pre-washing the zip can prevent potential shrinkage if you are using it in a garment made of natural fibers that may shrink significantly.
Ensure you are using a concealed zipper foot which uncurls the coil; if stitching manually, use a fingernail to keep the coil uncurled while sewing.
Check for loose fabric threads caught in the coil and gently back the puller out to clear the obstruction.
Ensure the zip is not being pulled taut by a tight garment fit; verify the stopper is secure if you have shortened the length.
For the best results, ensure you have a concealed zip foot compatible with your machine brand. Before installation, it is recommended to press the zip tape flat with a low-heat iron, taking care not to melt the nylon coil. When sewing, use a stitch length between 2.0 and 2.5mm for a secure bond. After the garment is completed, the zip can be machine washed; however, always close the zip completely before laundering to prevent the pull tab from catching on other fabrics or damaging the coil.
