YKK zipper, beige, 50cm, 12 pieces. As you can see from the image, these are high-quality, sturdy zippers. Neither the fabric nor the zipper itself is flimsy. I believe the quality is such that they might cost around 200 yen each (personal opinion). The reason for the low price is that I have a large quantity of these, entrusted to me from a sewing factory, hence this price. I will include two 48cm gray zippers as samples. You can change the gray samples to beige; please let me know in the comments after your purchase. Width is approximately 32.5mm (Image 3). There are markings that were used as a guide during sewing from the beginning. The markings are on the back, at the end of the zipper, so they will be hidden once sewn. The gray zippers do not have markings. These are suitable for clothing, but are also ideal for bags and interior items (cushion covers), etc. The slider is not metal, so you can sew the bottom stop with a sewing machine. Hardware to stop the bottom is also sold, so you can adjust the length yourself. I will lightly fold them and send them via Yu-Packet Post.
