The COSTUMAKERS Invisible Closed End Zipper 20cm (8") - Magenta - 1780 provides an ultra-slim profile for garments where discreet closures are essential. With an invisible #2.5 nylon coil embedded in ultra-lightweight tape, this zipper remains hidden beneath garment folds, ideal for dresses, skirts, and tailored pants. To install, use an invisible zipper foot and baste to align precisely, sew close to the coil without catching fabric edges, then test by zipping to ensure fluid movement. Press gently with a protective cloth to set the seam without harming the coil. Maintain an assortment of colours and lengths for on-demand customization, trim excess tape neatly, and grade seam allowances for refined, professional results.
