YKK #8 Heavy Duty Vislon Molded Black Separating Jacket Zipper - Choose Your Length - Color: Black - Made in The United States (1 Zipper Per Pack)

spent hours hand sewing the zipper onto a coat. zipper broke catastrophically after zipping it maybe 5-10 times. broke so bad I couldn't unzip it and had to cut the threads to remove it from my coat. the zipper it replaced was an exact match and lasted 10 years of wear.
