Navy Blue Heavy Duty #5 Invisible Continuous Zipper Tape

This rich navy blue shade is a classic, versatile colour ideal for dressmaking, dancewear, uniforms, school projects and soft furnishings. It blends beautifully with deep blues, nautical palettes, prints, and bold colour schemes while providing a strong but concealed fastening.

Each metre includes two matching sliders, allowing you to create a custom-length invisible zip with a professional, smooth finish. The Size 5 design features a durable 5 mm coil, making it stronger and more robust than standard Size 3 invisible zips — perfect for thicker fabrics and everyday wear.

Perfect for:

• Dresses, skirts and everyday garments

• Dance costumes & activewear

• Cushions and contemporary home décor

• Craft projects and bags

• Light upholstery

• Anywhere needing a strong invisible zip

All orders are cut as a continuous length from one reel.

Size 5 (or #5) refers to the coil width of 5 mm. This is stronger and more robust than a standard Size 3 invisible zip, making it suitable for bridal wear, costumes, cushions and upholstery projects where extra durability is needed.

Each metre includes two colour-matched sliders. Slide the tape into the channels and pull gently to secure.
