This is a ball bungee cord (bungee cord with a ball). It is used to secure tents, tarps, truck sheets, etc. It can be easily attached and detached by hooking it onto the grommets of the sheet. It is also suitable for securing sunshade screens. It is a set of elastic black cord and plastic balls, convenient for setting up tents and tarps. It is a used item, but it is in good condition with no particular damage. Thank you for viewing.
