The COSTUMAKERS Outerwear One Way Separating Zipper in Sept. Brown, 50 cm (20"), 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.
