The COSTUMAKERS General Purpose Closed End Zipper, Style 1700 in Bitter Red combines refined style with reliable performance for versatile garment applications. This 23 cm (9 in) zipper features a precision #2.5 nylon coil locked into a matching polyester tape, providing exceptional tensile strength and a smooth glide without bulk. The closed-end design ensures a neat, secure hem finish, while the nickel-free, corrosion-resistant slider enables snag-free operation through multiple wear, wash, and press cycles. Each coil is solution-dyed to ensure uniform, fade-resistant color across production runs, and all components exceed CPSIA lead-compliance standards and are tensile-tested beyond 20 newtons for safety and durability in both children's and adult attire. Installation is seamless with any standard zipper foot, allowing the tape to lie flat in seam allowances for a professional silhouette that resists distortion under steam or mechanical stress. Individually sleeved for protection against moisture and abrasion during transit and storage, the {color.lower()} zipper is ideal for fashion-forward designs, formalwear, and everyday attire requiring a dependable, low-profile closure.
