YKK AquaGuard Water-Repellent Zipper Demo
Just learning some random stuff this weekend. You know, I was wondering why so many zippers have YKK on them. So like many things I'm curious about, I just Google'd it and decided to watch a few videos. This one is about a special YKK zipper called the AquaGuard Water-Resistant zipper. Very interesting (to me!). :)
