Growing up in the 1980s I remember becoming mildly obsessed with zippers (or "zips" as we called them) at one point. I remember going around the house and noticing that it was strange that almost all of them, no matter what type of clothing it was, how old it was, or what size of zip it was, said YKK on them. Now days I guess they're more of a premium brand, but back then they seemed to totally dominate the market at all levels. (just checked the zip on my Lululemon trousers, and yes, it's YKK!)
