【If you're okay with shipping via regular mail, I'll discount it by 50 yen and sell it for 400 yen, so please comment if interested】 This is a set of two black flat knit zippers (40cm). Flat knit zippers are zippers that have elements (teeth) woven into a soft, thin tape made of knit fabric. They are suitable for use with thin fabrics and stretch materials, for draping in women's clothing, and the finish is beautiful because puckering is less noticeable. They are made of safe resin for children's clothing and are easy to use for clothes, bags, pouches, cushions, duvet covers, and cushion covers. *There may be differences in color between the actual product and the images. *I have a dog. *I do not smoke.
