No comments needed! Instant purchase welcome!! YKK Efron Zipper 3ER 18cm 3 pieces Light Gray This zipper has a nylon element woven into the tape. It is thinner than standard coil zippers, and is suitable for slacks, women's and children's apparel, etc. My parents run a sewing business, and I am selling these to clear out inventory. These are new, unused items, but have been stored for a long time. These are for professional use, so I believe the quality is not an issue, but please consider this before purchasing. 9
