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.
