Round elastic cords, often known as bungee cords or shock cords, are flexible cables that consist of a stretchable inner core covered by a woven or braided outer sheath. They are made to produce tension and flexibility for a range of uses, including attaching and securing objects. To meet diverse demands, Round elastic cords normally come in a range of diameters and lengths. Natural or synthetic rubber, which gives elasticity and stretchiness, typically serves as the core material.
