YKK | Onzichtbare rits met gesloten uiteinde | #2 | 12" / 30,5 cm

The automatic lock slider is a lifesaver—it stays put mid-zip, which makes installing it into a dress seam far less fiddly. Closed end means no fumbling with separating halves, and at 12 inches it’s the right length for a side closure.

Sewing this into a skirt hem went way smoother than I expected—the slider glides without catching, and once it’s closed, you genuinely can’t see the teeth. The 12-inch length fit my side seam perfectly, and the automatic lock holds tight even after a full day of wear.

I used this closed-end zipper for a dress project and was pleased how easily the teeth disappeared into the seam. The slider glides smoothly, even on delicate fabric. It’s a solid choice for a clean, professional finish.
