YKK | 開口拉鍊 | 成型塑膠 | 黑色 | #10

The teeth on this #10 zipper are massive and feel incredibly sturdy, which is exactly what I needed for a heavy canvas upholstery project. It glides smoothly even with thick fabric, and the molded plastic slider has a nice, secure lock.

This zipper is noticeably heavier duty than the standard ones I've used before, the molded plastic teeth glide smoothly. I'm using it to replace a worn-out cover zipper and it seems like it will hold up much longer.

The #10 teeth are chunky and feel rock solid — this thing slides apart and snaps back together cleanly every time. Sewed it into a heavy canvas cover and the molded plastic slider has held up through a week of constant pulling.
