Chinese rubber material make the bungee cord more elastic,lengthen 2 times easily.
But the resilience (the ability to regain its original shape after being extended),and the tensile strength (the ability to be extended under load without breaking) is limited.
Customers can buy these bungee cord nearly everywhere, cause their middle quality and reasonable price. We suggest use them only for light and temporary jobs, would be dangerous for heavy duty and long-time using. And you'd better check the cord condition before use everytime, as they're ageing quickly by sunlight in outdoor events.
