The COSTUMAKERS General Purpose Closed End Zipper, Style 1700 in Lavender blends refined appearance with industrial strength for versatile use. This 50 cm (20 in) zipper features a precision #2.5 nylon coil paired with matching solution-dyed polyester tape, offering exceptional tensile strength and a slim profile. The closed-end design ensures a clean finish at the hem, while the nickel-free, corrosion-resistant slider delivers smooth operation through repeated wear, washing, and pressing. All materials exceed CPSIA lead-compliance standards and undergo tensile testing beyond 20 newtons for long-lasting durability in both children’s and adult garments. Installation is seamless with any standard zipper foot, allowing the tape to lie flat in seam allowances for a polished silhouette that resists distortion under steam or mechanical stress. Individually sleeved to guard against moisture and abrasion during transit and storage, the lavender zipper is ideal for couture, bridalwear, formal attire, and everyday designs needing a reliable, low-profile closure.
