YKK | 分離型ジッパー | メタル | ブラック | #10

Finally found a #10 metal zipper with actual heft; the open-end design locks together perfectly for my heavy-duty upholstery project. Installed without any binding and the slider moves smoothly despite the chunky teeth.

These metal teeth are chunky and feel really sturdy, the one-way separating action works smoothly right out of the package. I'm using it for a heavy-duty canvas project, and the #10 size handles the thick fabric without jamming.

The #10 size is exactly what I needed for a heavy canvas jacket project, and the metal teeth glide smoothly without catching. The one-way separating action is perfect for a front closure, feels solid. Exactly as described.
