The COSTUMAKERS General Purpose Closed End Zipper, Style 1700 in Bitter Red delivers reliable performance and aesthetic appeal for dressmaking, skirt, and pant applications. The #2.5 nylon coil is precision-wound and sewn into a color-matched polyester tape that lies flat against delicate fabrics while providing exceptional tensile strength, flexibility, and durability under repeated wear. This lightweight, closed-end design features a low-profile, nickel-free slider for smooth, snag-free operation through multiple laundering and pressing cycles. Each coil is solution-dyed using industry-standard processes to ensure outstanding fade resistance and consistent color saturation across production lots. All components are fully CPSIA lead-compliant and undergo rigorous tensile testing above 20N to guarantee safety and long-lasting performance in both children's and adult garments. Installation is seamless with any standard zipper foot, integrating neatly into seam allowances and pressing flat for a professional finish. The Style 1700 zipper resists distortion when exposed to heat from steam pressing and is compatible with both industrial power sewing machines and domestic lockstitch setups. Each {color.lower()} zipper is individually sleeved for protection during transit and storage, making it ideal for bridalwear, formal attire, and contemporary fashion designs that require a bold, reliable closure.
