Yoshida Kogyo Kabushibibaisha, World's Largest Zipper Manufacturer???

Okay, so I was looking up random facts on the Internet, as I often do when I'm bored, and apparently Yoshida Kogyo Kabushibibaisha (YKK) is the largest manufacturer of zippers? Who would've known?!?! And I suppose most zippers have the letters YKK on them because of this..... I haven't looked yet to see if it's true but I assume it is... I don't know. I just thought I would share this useless bit of information with you. It could be lifechanging for someone. You never know.....

Tell me more random and useless facts if you have some! Don't be selfish! Share!
