The COSTUMAKERS Specialty Two‑Way Non‑Separating Zipper 50 cm (20 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.
