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 down with the zipper closed, for example. The zipper is separable and has two opposite sliders, so it can be closed up and down, i.e., in both directions. However, it can only be fully separated at the bottom. To ensure a long life for this zipper, it is important to always handle the two sliders with care: they must be aligned exactly at the bottom and pulled up slowly. Tip: If the zipper sticks, the following home remedies will make the teeth slide again: rub with soap, candle wax, or black pencil lead.
