Coil Zipper YKK Dark Jeans (398) 40CM Not Divisible

Coil Zipper YKK Dark Jeans (398) 40CM Nylon Not Divisible

This YKK coil zipper stands out immediately with its deep, understated denim tone that pairs beautifully with denim and dark blue fabrics. The tape features a fine, dense weave and the spiral teeth in matching colour create a quiet, cohesive look without harsh contrasts. The slider comes with an auto-lock mechanism that holds precisely where you position it, so the zipper won't slide open on its own. This is the finish you expect from YKK, made in Japan and refined down to every detail.

What is this material

This is a non-separating coil zipper, meaning the two sides are permanently joined at the bottom and cannot be pulled apart. The teeth are made from sturdy polyacetal plastic, formed into a fine spiral that glides smoothly without snagging. The woven polyester tape is robust enough to handle in construction yet supple enough for lighter garments. Size 3 teeth make this zipper suitable for refined applications where you don't want a chunky, obvious closure. The auto-lock slider engages automatically the moment you stop pulling, so your zipper stays secure during wear.

Uses

Thanks to its subtle colour and fine construction, this zipper is made for projects where you need a discreet yet dependable closure. Think about:

• Dresses and evening gowns with a hidden side seam zipper
• Skirts in denim or other dark blue fabrics
• Trousers and pants where a neat fly is important
• Cushion covers and small home decor projects
• Children's clothing where a soft, safe zipper is needed
• Bags and accessories with a clean finish
• Repairing and replacing existing zippers in garments
• Sewing projects where the colour needs to match denim or jean-blue fabrics
