This spiral has a length of 5m with a diameter of 8mm. This length is sufficient for covering long-length cables when devices cannot be next to their power supply. It is usually chosen for speakers that are far away from their source, for professional devices, for network installation products, etc.
With a spiral, you can organize the cables of your computer, phone, and television so that they are all together in one specific place. This way, the cables do not get tangled and take up less space, contributing to the overall organization of your space.
