YKK | 開口拉鍊 | 尼龍螺旋 | 雙向 | 黑色 | #5

I needed a two-way zipper for a heavy jacket repair, and the #5 teeth on this nylon coil feel sturdy enough for daily use. The open-end design makes it easy to attach and separate, and the sliders move without catching. Perfect fit for the project.

Finally a separating zipper with a proper two-way slider that actually works smoothly on both ends. The black nylon coil looks clean and the #5 teeth feel substantial enough for my heavier jacket project.

The two-way slide on this open-end zipper works exactly as it should, and the #5 teeth glide smoothly without catching. I've already replaced two broken jacket zippers with these and the black nylon coil looks clean.
