YKK’s smallest* zipper ever!
-
The MINIFA™︎ zipper is the smallest and thinnest zipper out of all YKK products.
Just a millimeter thick! It is used for things such as inside jacket pockets.
The parts of the MINIFA™︎ zipper are extremely small, as well, and being able to make them precisely is the result of YKK’s technology capability.

A zipper that stretches vertically!
-
The SOFLEX™︎ is, amazingly, a zipper that stretches vertically.
By employing stretch fabric in the tape and incorporating specialized design features into the elements, we made vertical elasticity possible.
-
A one kilogram weight stretches it
by about 10%!! -
When a one kilogram weight is suspended from a SOFLEX™︎ zipper, it stretches by approximately 10%.
Despite stretching this much, the zipper has both the strength and flexibility to prevent breakage, making it perfectly suited for use with stretch fabrics. It is used in sportswear that moves with the body, as well as clothing that is very form-fitting.
