The COSTUMAKERS General Purpose Closed End Zipper, Style 1700 in Grotto embodies rich, muted depth with reliable performance. At 55 cm (22 in), it employs a #2.5 nylon coil woven into ultra-durable polyester tape, delivering superb tensile strength and consistent coloration. Its closed-end design provides a tidy, snag-proof finish that’s perfect for lightweight to midweight garments. The nickel-free slider resists corrosion and glides smoothly in daily use and repeated laundering. Each production batch is tested to exceed 20 newtons of pull force and meets CPSIA lead-free safety standards for both children’s and adult wear. Installation with any standard zipper foot yields flat, puck-free seams, and moisture-resistant sleeves protect each unit until needed. Grotto adds a sophisticated, stone-inspired accent to dresses, skirts, pants, and artisan-crafted pieces.
