The COSTUMAKERS General Purpose Closed End Zipper, Style 1700 in Smoke Grey intertwines refined design and industry-standard durability for superior garment construction. This 40 cm (16 in) zipper features a precision #2.5 nylon coil embedded in a color-coordinated polyester tape, ensuring exceptional tensile strength while maintaining a sleek, low-profile appearance. Its closed-end configuration provides a seamless, secure hem finish, and the nickel-free, corrosion-resistant slider glides smoothly through repeated wear, wash, and press cycles without snagging. Each coil is solution-dyed to guarantee uniform, fade-resistant coloration across manufacturing batches. All materials adhere to CPSIA lead-compliance standards and undergo tensile testing above 20 newtons for reliable performance in both children's and adult apparel. Installation is effortless with any standard zipper foot, allowing the tape to lie flat within seam allowances for a crisp silhouette that resists distortion under steam or mechanical stress. Individually sleeved to protect against moisture and abrasion during transit and storage, the smoke grey zipper is ideal for couture, formalwear, bridal projects, and everyday fashion that demands a dependable, low-profile closure.
