YKK | سحاب مغلق النهاية | بلاستيك مقولب | أسود | #5

I'm using this #5 YKK closed-end zipper to replace the back zipper on a worn-out duffel bag, and the molded plastic teeth slide smoothly without catching. The black finish matches perfectly, so I don't have to fuss with fabric paint — and it feels sturdy enough to handle daily use without jamming.

Bought this #5 non-separating zipper for a backpack repair, and the molded plastic is sturdier than I expected—definitely holds up better than the cheap metal ones I’ve used before.

The molded plastic teeth glide smoothly, and the closed-end design is perfect for my duffel bag repair. Only gripe is that #5 is a bit chunky for lighter fabric, but it feels solid and should hold up fine.
