YKK zippers, beige, 50cm, 12 pieces + 48cm gray, 2 pieces (see last image) I believe the quality is around 200 yen per piece (personal opinion). The reason for the low price is that these are items entrusted from a sewing factory, and I have a large quantity. Width is approximately 32.5mm. These have markings from the factory for sewing guidance. The markings are on the back, at the end of the zipper, so they will be hidden once sewn. These are sturdy zippers, perfect for bags, interiors, and more. They will be lightly folded and sent via Yu-Packet Post.
