KKF | 閉口拉鍊 | 金屬 | #3 | 6.5 英吋 / 16.5 公分 | 黑色

The zipper slider locks automatically, so I don't have to worry about it slipping down when I wear these trousers. The metal teeth feel sturdy and polished, and the 6.5-inch length was exactly what I needed for this skirt alteration.

Took a chance on these for a dress with a tricky side seam and the 6.5-inch length was spot-on. The metal teeth feel solid and the automatic lock holds perfectly, so no wardrobe malfunctions here.

The automatic lock on the slider is a godsend—it holds perfectly in place mid-zip, so no more wrestling with a skirt that keeps sliding down while I'm sewing. The metal teeth feel substantial and glide smoothly over the fabric, giving the finished dress a clean, professional look.
