YKK is the originator of zipper industry. YKK stands for the industry standard. Because of its adoption of Japanese elaborate workmanship, material and managerial method, the price of YKK is nearly 10 times of other branded zippers. YKK is still the biggest market share owner in zipper industry because of its non-replaceable high quality. Most factories are reluctant to use YKK on bags because the price of YKK zipper is very high and usually there are many zippers needed on a bag, thus the cost is very high. However, pursuing perfect is our target; we won’t leave any flaws on our products, so we choose YKK.
