The COSTUMAKERS General Purpose Closed End Zipper, Style 1700 in Topaz blends elegant design with durable performance for versatile garment applications. Equipped with a precision #2.5 nylon coil locked into color-matched polyester tape, this 23 cm (9 in) zipper offers optimal strength and smooth glide without bulk. Its closed-end design provides a neat, secure finish at hems, while the nickel-free, corrosion-resistant slider delivers snag-free operation through extensive wear, laundering, and pressing cycles. Each coil is solution-dyed to ensure uniform, fade-resistant colour across production runs. All components exceed CPSIA lead-compliance standards and undergo tensile testing above 20 newtons to guarantee reliability in both children’s and adult garments. Installation is seamless with any standard zipper foot, allowing the tape to lie flat within seam allowances for a professional silhouette and resisting distortion under steam or mechanical stress. Individually sleeved for protection against abrasion and moisture during transport and storage, the topaz zipper is ideal for bridalwear, formal attire, couture, and everyday fashion requiring a high-performance, low-profile closure.
