No comments needed! Immediate purchase is welcome!! YKK Efron zippers, 18-21cm, 11 pieces total 18cm: Moss green 1, Blue gray 1 20cm: Navy 1, White 2, Beige 1, Black 2 21cm: Red 1, Brown 1, Dark gray 1 These zippers have nylon elements woven into the tape. They are thinner than standard coil zippers and are suitable for slacks, women's and children's apparel, etc. My family runs a sewing business, and I am selling these to clear out inventory. These are new, unused items, but they have been stored for a long time. They are professional-grade items, so I believe the quality is not an issue, but please consider this before purchasing. O
