These quality YKK zippers have a lot more going for them than just function: they're made from 100% recycled materials! The tape, teeth, and cord are all made of recycled nylon and polyester, making this one of the most sustainable zippers currently on the market, and we are proud to make them available to you. Each zipper is 22" or 56 cm long and can easily be shortened by sewing a dense zig zag as a new zipper stop.
