Nylon Closed End Zipper

These are great for adding to silicone masks to create an easy on off mechanism...

Nylon Closed End Zippers come with an enamel, automatic locking slider. This means that the only way to open or close this zipper is by using the enamel pull. Additionally, at the bottom of the zipper, there is a colored stopper that prevents the zipper from opening further and keeps the zipper from fully separating.
