YKK Conceal Zipper 50cm 20 zippers total, 2 of each of 10 colors. These are unused items, but they have been stored for a long time. Some items have creases, wrinkles, and stains from the storage bags. Some sliders are discolored. Also, one zipper is missing a stopper. I will include 3 spare stoppers in a small bag. Please consider purchasing after understanding the above.
