White Heavy Duty #5 Invisible Continuous Zipper Tape

This crisp white invisible zipper tape is perfect for bridalwear, dance costumes, children’s clothing and clean, fresh dressmaking projects. It blends beautifully with pure white fabrics including lace, satin, tulle, cotton, and stretch materials, while keeping the fastening completely concealed.

Each metre includes two matching sliders, allowing you to create a custom-length invisible zip with a flawless, professional finish. The Size 5 coil features a strong 5 mm width, offering more durability than a standard Size 3 invisible zip — ideal for thicker or structured garments.

Perfect for:

• Wedding dresses, bridesmaid wear & formal garments

• Dancewear, performance costumes & uniforms

• Everyday dressmaking & children’s clothing

• Cushions, craft projects & fresh home décor

• Any project needing a clean, bright, concealed 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.
