This cable organizer is a highly practical and versatile solution for managing various cords. It has a diameter of around 0.3 in. (7.5 mm), which enables it to hold a wide range of cords, like Type-C charger cords, lightning cords, HDMI cords, USB cables, and more. The magnetic locking design is both user-friendly and secure. The magnetic grasp allows for easy cord insertion, and its strong magnetic lock firmly holds the organizer, preventing any charging head from falling off and ensuring smooth cable pulling. The use of a strong Pro PET sticky pad is another highlight. It offers excellent adhesiveness, firmly sticking to smooth and dry surfaces such as wood, glass, or ceramic tiles. When removed, it leaves no residue and causes no surface damage. This organizer is great for keeping cables organized. It holds cables firmly in place, keeping them off the floor and allowing you to arrange cords in neat traces as you desire, whether on an office desktop, tableside, or even on a car dashboard. For installation, simply clean the surface to be free of dust before sticking and press for 30-seconds. Waiting 12-24 hours after installation is recommended to achieve the best performance. In short, this cable organizer combines functionality, convenience, and ease-of-use to solve the common problem of cable clutter. Material: Plastic.
