Professional 18" (45cm) Invisible Zips: Extra Length for Extra Quality When working on large-scale sewing projects, the zipper is often the point of failure. Our 18-inch #3 Invisible Zips are engineered to handle the demands of larger surface areas while remaining completely undetected. Whether you are crafting luxury floor cushions or an elegant evening gown, these zippers offer the perfect blend of length, strength, and subtlety. The Power of Woven Tape on Long Seams Longer invisible zips are notoriously difficult to install because the fabric can shift or pucker over the 18-inch run. Our Woven Tape base provides a firm, stable foundation that grips your fabric, preventing the "wavy" effect often seen in cheaper zippers. The result is a crisp, flat, boutique-standard seam every time. Versatile Home & Fashion Applications The #3 gauge coil is slim enough for delicate silks and satins used in bridal wear, yet robust enough for the heavier linens and upholstery fabrics used in high-end interior design. Perfect For: Large Soft Furnishings: The standard for 18" to 20" decorative cushions, bench pads, and floor pillows. Evening & Bridal Wear: Ideal for the long back-closures of gowns, jumpsuits, and formal dresses. Removable Covers: Great for seat pads and headboard covers that require a discreet, long-length opening. Technical Specifications: Length: 18 Inches (approx. 45cm) Zipper Type: #3 Invisible / Concealed (Closed-End) Tape Material: Professional-Grade Woven Polyester Quantity: 5 Zips per pack Maintenance Note: For long-lasting performance, we recommend unzipping the closure fully before inserting or removing heavy cushion pads to avoid unnecessary tension on the bottom stop.
