As described! Will order from seller in the future
I got them working in the end but had to modify them a bit. My zippers are too thick for these sliders. The sliders are the right width, but they squeezed the zipper so hard that i couldn't move the sliders. With a tiny file i increased the depth of the passage for the zipper in the metal sliders until the sliders went smooth. All fine now. For your zipper these may work without modification. It all depends on how thick your zipper is i suppose.
