YKK zippers, 50cm beige x 10 + 48cm gray x 2 As you can see from the images, these are high-quality, sturdy zippers. Both the fabric and the zipper itself are not flimsy. These are from a sewing factory, and I have a large quantity, hence the price. Width is approximately 32.5mm. These have markings that were used as a guide during sewing. The markings are on the back, at the end of the zipper, so they will be hidden once sewn. The gray ones do not have markings. They can be used for clothing, of course, but are also ideal for bags and interior items. The slider is not metal, so you can sew the bottom stop with a sewing machine. Also, the hardware to stop the zipper at the bottom is sold separately, so you can adjust the length yourself. They will be lightly folded and sent via Yu-Packet Post.
