About this material

This coil zipper is a non-separating zipper, which means the two sides stay connected and cannot be pulled apart, ideal for closures that don't need to open completely. The teeth are made of plastic (polyacetal) and run in a fine spiral form, so the zipper glides smoothly and bends easily without catching. The tape itself is polyester, strong yet flexible enough to move with the fabric you're sewing it into. Because of the compact tooth size, this zipper works well for light to medium weight fabrics where you want a discreet closure. The automatic locking on the slider keeps the zipper in place once you let go.

Uses

This black YKK zipper is a real workhorse in the wardrobe and home. Think of projects like:

• Evening gowns and cocktail dresses
• Skirts with an invisible side seam closure
• Trousers and pants
• Cushion covers and decorative pillows
• Small home projects like bags and pouches
• Sewing projects where a clean finish matters
• Repairs on existing garments
