The COSTUMAKERS Specialty Two-Way Non-Separating Zipper 55 cm (22 in) in Black (1745) features #5 silver metal teeth for lightweight strength and durability. This non-separating design allows opening from either end while keeping the chain connected, making it suitable for overalls, jumpsuits, and workwear. The two-way functionality provides flexibility for ventilation and movement. Precision-made teeth ensure snag-free operation, while the woven tape remains stable during sewing and wear. An excellent choice for garments needing controlled access points without full separation.
