Continuous coil zipper chain No. 3 (4 mm) is available per spool, that is shown in the product image.
The continuous coil zipper chain is a fine-toothed coil zipper with a smooth zip. Coil zippers are more flexible than block tooth zippers, making them an excellent choice for projects with curves. Use coil zipper on pillows, small seating cushions, small purses or bags. Continuous zippers require at least one end to be sewn shut and do not include a starter box, pin or top stops. At the top of the zipper, sew the end shut or sew on fabric tabs as zipper stops. Zipper slider sold seperately.
