Do you know why zippers have YKK on them?

The zipper (zip) is one of those clever inventions that we all take for granted, cleverly aligning two jagged strips of metal (called teeth). It wasn't until 1917 that it was patented and whilst this device looks relatively simple enough, we still live in a world with faulty zippers, teeth that break and ones that just don't stay up!

There are a number of manufacturers in the world however brands who demand consistent quality for their garments and products ultimately seek out the best. There is one single manufacturer who astonishingly makes almost half of the zippers on earth. That equates to over 7 billion per year.

Whether it is a zipper on your clothing, your bag, your luggage, sports equipment or your furniture coverings, you may have not realized that it will very likely be boasting the initials YKK.

YKK Zipper Facts

Did You Know The YKK Zipper Factory:

  • Makes 7 million zippers a day
  • In 1,500 styles
  • Over 427 standard colors
  • Largest zipper factory in the world
  • Produces its own brass to make the teeth and slider parts of the items.
  • Makes machines that make the zippers

YKK on zippers stands for Yoshida Kogyo Kabushikikaishaa

The YKK found on over 7 billion zippers produced every single year stands for Yoshida Kogyo Kabushikikaisha. The name of the founder of the Japanese zipper company.

The company was founded in Japan in 1934 and whilst its main office is in Japan it is made up of 80 companies located at over 206 facilities in 52 countries around the world.

The factories make the entire zipper including the cloth and the brass used. It's incredible.

Are There YKK Counterfeits?

As cheaply as this items is actually produced, ironically, there are fakes or counterfeit YKK zippers on the market. Given its tiny stature, it is very difficult to identify the true one from the imposter other than to say the true YKK zipper will definitely last longer.
