As the name suggests, the self-locking nylon tie will only lock more and more tightly. Generally, it is designed with a stop function. However, if someone accidentally locks the wrong place, please don’t worry and pull hard to avoid damage to the locked object. We can try to unlock it. 1. Cut it with scissors or knife, which is convenient and fast, but can not be reused. 2. We can find the head of the tie, and then gently press it down with small or fingernails, so that the tie will be automatically loosened and opened slowly.
