These cable ties are really easy to use. Just wrap them around the cables you want to organize and pull the end through the locking mechanism until it's tight. When using, make sure not to pull too hard as it might break the tie. For maintenance, keep them in a dry place away from direct sunlight. This will prevent them from getting brittle over time. And if you're not using them right away, you can store them in a box or a container to keep them organized.
