KKF | Endlos-Reißverschluss | Metall | 5" / 13 cm | Dunkelblau

I’ve been using this closed-end zipper for a pair of dark denim shorts, and the polyester tape is sturdy without being stiff—feels nice under the sewing machine. The antique silver teeth match perfectly with the dark blue, giving it a polished look that’s hard to find in standard zippers.

The slider catches cleanly every time I zip my jeans, and that closed end means the bottom won't split no matter how much I tug. The dark blue tape blends right into the denim, which is exactly what I needed for a repair.

The antique silver teeth on this are really nice – gives a subtle vintage look while still being sturdy. Slider locks smoothly, so no slipping when I sit down. Worked perfectly for the skirt alteration I was doing.
