Upgrade your projects with a premium COSTUMAKERS zipper. This 55 cm one-way separating model features #5 brass metal teeth on heavy‑duty polyester tape for smooth operation and reliable strength. The black finish coordinates beautifully with both contrast and tone‑on‑tone fabrics, while the precision‑cut tape offers consistent width so every installation is trouble‑free. Engineered to resist corrosion, UV fading, chlorine bleach, and repeated machine‑wash cycles, it keeps garments looking sharp and operating flawlessly. Ideal for parkas, wool coats, ski jackets, leather jackets, and rugged outdoor gear, this zipper’s easy‑grip pull lets you suit up quickly and stay comfortable on the move. Every COSTUMAKERS piece is batch‑tested for tensile‑strength and slider fatigue, giving makers confidence that their work will endure season after season. Whether you’re replacing a broken closure or finishing a brand‑new design, choose the zipper trusted by industry professionals for tight tolerances and colour consistency.
