The COSTUMAKERS Outerwear One‑Way Separating Zipper 35 cm (14 in) in Black (1747) is built around robust #5 antique‑brass metal teeth that balance strength with a refined fashion look. It features a one‑way separating bottom so the wearer can fully open the garment hem—perfect for coats, casual jackets, and fashion outerwear. The slider uses a drop pull for easy handling and a confident feel, while the precision‑formed elements mesh cleanly to resist snagging when passing thick seams and facing layers. A durable woven tape supports the chain, lying flat for professional installation and top‑stitching. This medium‑weight gauge is a shop favourite for everyday outerwear because it tolerates repeated cycles without tooth deformation and keeps a smooth run after laundering. Suitable for new construction or replacement work in apparel, costumes, and craft projects where antique‑brass styling is desired. Coordinates with 1746.
