It is flexible and easy to block. You just have to pull its tail slightly and then it locks automatically. Save time - its self-locking ensures that you work efficiently. Save your worries: it stops at the desired length and never slips. What's more, it's cost-effective - one bundle of ties equals many times of use. All you need to do is choose the correct size.Use and creativity: In daily life, you can use them to pack materials, fix plant branches, repair garden fences. In the office and workshop, they can be used to organize electrical cables, hang LED lights and banners. You can even do some creative projects: shaping a butterfly or fish for kids; present your fashion design of a zipper dress. You can also buy a zip fastener with a label for writing. After writing numbers on the tag and locking it to cables, bags or clothes in order, they can be easily recognized.
