YKK | 分離型ジッパー | メタル | 両開き | ブラック | #5 | 21インチ - 53 cm

The metal teeth have a nice weight to them, and being an open-end two-way zipper makes it perfect for my jacket project. Stitching through the fabric tape was clean and easy.

The slider moves smoothly even on thick fabric, and being able to open it from both ends is a lifesaver for my jacket repair. The metal teeth feel solid and the black finish matches perfectly. I'll grab another one for my next project.

Finally found a metal #5 with proper two-way action; the teeth mesh cleanly every time. The open-end design makes it easy to swap out on a jacket I’m repairing. Black finish looks sharp against the fabric.
