The COSTUMAKERS Outerwear One Way Separating Zipper in Navy, 60 cm (24"), is built for heavier outerwear projects that benefit from a strong, reliable front opening. It features #10 silver metal teeth for durability at stress points, and the one‑way separating design allows full opening at the hem. Support the placket with interfacing, verify alignment at hem and collar, and stitch with a zipper foot for a smooth run. Follow garment care guidance and protect the fabric with a press cloth near metal components.
