Our 5 mm two-way zipper with 2 metal sliders from YKK is a modern zipper for jackets and coats that gives you more space at the hem of the coat, making it more comfortable to sit with the zipper closed, for example.
The zipper is separable and has two opposing sliders, allowing it to be closed both upward and downward, in both directions. However, it can only be completely separated at the bottom.
Important for the long life of this zipper is the careful handling of the two sliders: they must be aligned perfectly at the bottom and pulled up slowly.
Tip: If the zipper gets stuck, the following household remedies will help make the teeth glide again: rub with soap, candle, or black pencil lead.
